17:10 That reason was because Germany had no helium of it's own. The only country at the time with large helium reserves was the United States and Germany had made a deal to buy helium from them but at the last minute the United States changed it's mind.
Fun fact I learned about the cellphone myth. When your cellphone tries to connect to a tower it uses a decent amount of power. When it fails to connect it tries again, increasing the power. This is called "power ramping" and is also one of the reasons why putting your airplane mode makes it use less power. While it does this it is possible that this can disrupt networks on the ground.
When it comes to cellphones, remember that old cellphones were analog and used very different frequencies that were capable of causing interference with aviation instruments. It’s less about causing a plane to lose control and more about the tiny deflection in the instrument needles that, over 100’s to 1000’s of km’s, becomes a big problem. The early days of cellphones were actually the 80’s and it was a lot less regulated and a little more Wild West. They understood how instruments worked and how cell phones were being produced and said, “There’s possibility for interference and the pilots wouldn’t know until it was a problem,” so they banned their use. People don’t want to believe something as simple as a cellphone can cause a significant navigation issue, but it could’ve. More so in the early days, than today. The issue also being that a cellphone is more likely to get a signal during the key stages of flight, during take off and landing. Once flying, the altitude and speed of the plane become a problem when connecting to a tower. Today, they ask you to turn off devices so you pay attention during takeoff and landing. It’s the same reason you are asked to sit up, put your stuff away and open the windows. You are alert, paying attention and clearing the way should there be an emergency. I wouldn’t want to test the cellphones of the 80/90’s in those decades. Planes tend to lag in technology by 10-20 years. But today? I’m confident your cellphone is fine. But turn it off and pay attention to what’s going on around you.
Well, one point they didn't bring up about the cellphone interference is that not all planes are maintained at 100% all the time. If for example some of the shielding was compromised from rodents chewing it, accidentally rubbing against something and causing damage, then Grant's test in the cage showed that it definitely could cause problems
@@MrXeCute No, it doesn't, by definition, a zeppelin is long and cylindrical in shape and with a rigid framework, no wings, has an engine and contains a gas mixture to make it lighter.
Basicly a Zeppelin is an airboat. So it can be a raft... What they tried to do in a smaller scale, is a raft... but you need too much uplift power, provided by helium to be proficient (you need more square meters to provide that kind of uplift). Learn some basic physics. Basic education in the EU btw. ;)
well back when phones first came they did interfere allot with electronics around them. when ever you where about to get a call your TV would make a strange noise before your phone even starts ringing. so i think this was just something left over from the late 1900s when phones could cause problems and it just took a while to get regulations to change. but today tech is so advanced that phone signal poses no threat to other electronics and regulations have cought up which is why you can now have your electronics running on the plane.

But if you’re disruptive in an air born airplane, then you’re stuck there whether the other passengers like it or not… And it could possibly cause a fight between passengers if you refuse to shut up, which is obviously the last thing the flight attendants want to deal with every single flight isn’t it..? So they just tell you to turn it off for the “safety of the aircraft” so that they can avoid all of the possible/probable drama from people talking loudly on the phone for hours and hours whilst other people are trying to sleep and rest… I’ve always said that this is why they tell you to turn your phone off, and I stick by this no matter what😂 I refuse to believe that I’m not at least PARTLY correct in my theory here???
There is no signal once you reach a certain height, and they generally never tell you to turn the phones off - just to put it in airplane mode. Moreover, a lot of airlines provide onboard wifi, so you could easily annoy your fellow passengers having conversations online if you felt like it.

For anyone curious I looked into that Zurich crash, they did investigate phones, but it turned up nothing, it did not cause the crash. What's more phones have never been *definitively* shown to cause enough EMI to affect instruments in flight. There *are* a few studies that suggest that in lab conditions it *may* be possible especially on older hardware, and there are anecdotal reports of some specific devices causing issues on real flights, but it's hard to corroborate these.

There are a few phones that do cause really bad radio interference. Blackberry phones from 2008 to 2012ish all caused a lot of radio interference (like a buzzing static) whenever you'd get a call.

20,5 cubic FEET... So the big one will be 3000 cubic feet and 30 cubic fingers so that's 750 cubic legs and 17 heads. Imperial mesurement system is so dumb
"...but for some reason [...] it was filled with flammable hydrogen instead." That reason being the US, at that time the only source of a sufficient amount for airship needs, not selling Helium to Germany because of that toothbrush-moustache wearing guy and his henchmen being in charge there.
The US started to ban exports to ANY country in 1925 (so 8 years before the Nazis took power and Germany). It wasn't because of moustache-man and his henchmen, since in 1936/37 the crimes which they were committing/are going to commit weren't really known yet to the outside world.
5:30 the math is wrong. In this case it's as simple as dividing the molar masses of each component with one another since the amount of particles (moles) in 1 L of gas is the same regardless of the type of gas used. Hence you can calculate the ratio as such: Ratio = M(N2)/M(He) = 28/4 = 7 Which tells us that 1 L of N2 (dinitrogen - how nitrogen bonds with itself in nature) is 7 times heavier than 1 L of Helium. Not 10 times .. 7. Now, air is 78% N2 mixed with 21% O2 (Oxygen) where the last 1% is (roughly) Argon, a noble gas that - like Helium - does not bond with itself in nature. Hence we can estimate the ratio a bit better: Ratio = (M(N2)*0,78+M(O2)*0,21+M(Ar)*0,01)/M(He) = (28*0,78+32*0,21+40*0,01)/4 = 7.24 Which leads us to the conclusion that atmospheric air is approximately 7.24 times heavier than Helium.
20:00 - My hypothesis here is; the reason why the tubing goes "flaccid" and appears to lose pressure is because of the relative difference in air temperature from outside to inside. I would bet money on this being a major factor. the other reason would be that, yes, helium does leak out on plastics naturally, but with the tubing that they have chosen in the show, I would hazard that I would be negligible and that you might expect to lose 1-2% volume every 12-18 hours. this is unlike latex balloons under constant tension and hoop-stress, and mylar balloons which are much thinner and less GSM and designs for balloons in small volume party applications. I'm fun at house parties.
@@themonsterunderyourbed9408 well it's run by the company that holds the actual distribution rights to the show so I feel like that's pretty official.
@8:51 where the commentator says "the more helium you have the more air it displaces and the greater the lift" that is not true, if it was the case then the gas bottle it comes in would be floating away. It's about volume displacement. As you inflate a normal latex balloon, the greater the pressure is needed to expand that balloon, the more helium you add will only make it heavier as the pressure builds inside, that's why weather balloons are made out of a thinner, more expanding material.
It would be nice to have it in the language of other countries. Here in Brazil it was rare to have it since the first season. To watch on the internet. I am addicted to the series and I miss it a lot.
20:12 One advantage they had with the lead balloon is that lead, even when extremely thin is so dense that it doesn't allow any gasses to pass through. Lead is one of the most non-porious things we have.
Interstingly, the "cellphones cause airplanes to crash" myth has actual validity in the present days. 5G services in America operate close to the frequency band used by radar altimeters (3.7-4.0 GHz and 4.2-4.4 GHz respectively), which may cause the above-ground altitude reading to become unreliable. That instrument is primarily used during landing, which sounds bad, but the worst that can happen (assuming a competent flight crew) is a go-around if the pilot can't stabilize the approach. The FAA has certified most aircraft to be safe from this interference, though. Flying within a 5G tower's range is far less risky than being a Boeing whistleblower (0:2 fatalities). European 5G towers don't have this effect because they operate on a lower frequency band of around 3.4-3.8 GHz.
Thing is the main characteristic of 5G is that it only works on shorter distances. So there's no way it'll be a problem in the air. As you pointed out the instrument that it could interfere with is something that really only gets used during landing to help with line ups. It shouldn't have much of an issue distinguishing the signals in that kind of environment.
@@StorymasterQ just wait for the door to open mid-flight. Or for the engine to return to ground without the plane. Or for the computer to decide that you should go into a vertical climb.
phones on planes is nonsense, but i'd really like to see someone test by getting volunteers with multiple phones, put them into a big passenger plane that takes 150+ passengers, get plane ready for take off (so it's fully functionaly) and then tell volunteers to use their phones as much as they can. make calls, send texts, use gps ..etc. if 150+ phones won't cause any interference, then nothing would.
17:15 The reason why the Hindenburg used Hydrogen and not Helium is the US government. The US were the global main supplier of Helium in those days and did not want to sell any to Hitler's Germany, so the Hindenburg had to use hydrogen, which was easy to produce.
The only thing that was busted were their clueless attempt when removing ballast, and just cutting away from one side without any awareness of balancing it and seems no straps was fitted to pull it down, so one side just raised to the ceiling and no way to pull it down. thats a shame when they conclude "busted" for that "raft" when in wasn't and it clearly would work, as it did on paper - as the lifting power was there, and simply failed from own mistake. Kudos for effort, but also weird they didn't use any planning when it came to the rigging for controlling it.. just as much Adam & Jamie's error for not guiding and not just Kari Byron cutting the wrong ballast 46:55
@cejannuzi yeah,I know..but they always do that with every myth..they take it to extreme just to prove it's impossible to confirm a myth under normal circumstances
if one cell phone call could take down a plane, I'm pretty damn sure they would take your cell phone away from you before you boarded. same reason why you can't take a bomb onto a plane.
You do understand how old this show is right? Things change, technology changes. Its not so much that it would crash the plane as interfere with the electronics and instruments. I mean, if you were driving your car and your speedometer didn't work well thats not going to cause you to crash but you probably still don't want to drive like that.
@@Damaged7 Nonsense, even old planes were tested for RF interference, due to things called "lightning", which emit RF signals a million times stronger than a cell phone. (And no, an airplane is not a perfect Faraday cage - it has windows where external RF signals can get through.) Cell phones were banned primarily because it was the perfect kind of security theater that also helped the bottom line.
@@i.m.9823 it’s about altering the signal being received and giving false information versus causing the plane to crash. As an example of sensitivity, Nickel ore cause significant compass deviations and flying around the northern edge of Lake Superior and Huron can cause, up to 15° compass variations because of the High nickel content in the ground. The original instruments used for navigation were very sensitive. Planes needed to be tested with all equipment on, to determine how they interfered with each other. A small needle deflection due to interference can have huge consequences over 100’s to 1000’s of km’s. The instruments don’t need to go wild, in fact, that would be ideal because the pilot knows there is a problem. What’s more an issue is a small deflection that the pilot wouldn’t notice and it’s a very tiny window to cause problems. Aviation relied solely on radio frequency instruments up until about 15 years ago. Even though GPS was around before that, it was usually a supplemental tool until very recently and even today, it’s mostly classed as a secondary instrument, even though it’s practically used as primary. Pilots use both, but if there is a conflict in information, there really isn’t a way to test GPS is off, other than using instruments that rely on frequencies and because most planes have more than one frequency based instrument. GPS has more issues than people think and the radio instruments proved to be more accurate and reliable for 50-60 years, already. That, and it took a long time to update the whole system, to start switching to gps. Old phones were not as shielded and the regulations on which bands they could use, were not as strict/followed. They operate far more as an analog device than the digital devices we have today. The aviation industry knew for decades that other electronics can cause deviations in the instruments. With the advent of cellphones it became a concern of “We can’t be sure if that phone is safe, but we know similar devices can cause problems, so we want to to turn it off.” Today, I’d say your phone is safe, today. I have an older plane and fly with my cellphone on, I don’t fly relying on instruments and fly by visual flight rules (VFR). Oddly, one of the biggest instrument errors I’ve seen was putting my hand up on the instrument dash, next to the floating compass, and the nickel in my ring turned the compass s about 30°. Why do you still need to turn it off? Because they want you paying attention to landing and take off and when you are in the air, you are too high and too fast to keep a signal. I fly at 4000’ and have a hard time getting a signal for more than 4-5 minutes.
Would you two like to revisit all draws or ties and redo them to get a winner? I think that would be cool with how things have changed since the show aired
The narrator saying Grant should get some tin foil underpants was funny but True! Did he ever have children? I don't think that all that radiation can be good for you. 😮
The helium raft would made more sense if they just strapped it all under a huge net and fitted a platform under the net that Adam could walk into, essentially just a hot balloon.
Different tech, and you no doubt used a satellite mesh network on the plane, as well. Proof positive that tech is really cool, and laws have to catch up.
It's okay, Mythbusters team. Sometimes you have days like this. Two myths with disappointing ends in the same episode. At least you got the data you needed.
FAA is very conservative organisation. If there was any case of interference between some avionics and cell-phones or even possibility of such then restrictions probably will never be canceled.
Regulations certainly don't allow them to blast their plane disturbing frequencies in the open. Unless this is more controlled than this video suggests this is up there with just pointing lasterpointers at airplanes.
"the only finite resource in[sic] earth"? _Everything_ on the earth is finite. Even sunlight is finite. It won't stop for millenia yet, but it will stop at one point. Entropy has the final say anyway.
The Hindenburg wasn't designed to take helium! It wasn't a case of _craaaazy_ Fritz whimsically deciding to hook her up to the hydrogen tank instead of the helium that week(!) She was designed for hydrogen because, at the time, the States had a near monopoly on helium production and refused to allow any to be exported by law!
Iirc correctly, the real reason planes don't like cellphones is because mobile stationary stations not really like 300+ signals connecting and disconnecting around the same time due to a plane full of phones flying over.
At 17:02 “..for some reason… it was filled with Hydrogen…”. From Wikipedia “Because of the Helium Act of 1925, which banned the export of scarce helium on which the US then had a production monopoly, together with the prohibitive cost of the gas, German Zeppelins were forced to use hydrogen as lifting gas, which would gain infamy in the Hindenburg disaster.” Some reason uh, you didn’t gave it to them, that’s the reason.
is this helium which is so light that Earth literally can't prevent it from leaving the atmosphere into space, the stuff we need to run MRI scanners? naaaa it's probably different helium right
cellphones are not allowed on plane cuz they want you to use extremely expensive plane phone, that's all there is. if phones were so dangerous to planes, they wouldn't allow you to keep it on you while in flight. its common sense. another common sense moment, is that cellphones output a very, very weak signal, while the towers output thousands of times more powerful signal, so if cellphone signal was dangerous to planes, then planes would fall down when they're closer than like 10km to any cell tower. cell tower sends extremely powerful cellphone signals, while phone itself doesn't even have powerful enough battery to send that powerful signal, therefore it is impossible for it to effect the plane. i think only other reason why they tell you to turn it off or on airplane mode, is same reason as what happens when you put cellphone close to a speaker and then there's incoming/outgoing cell signal (like sending/receiving sms or calling). it has to be quite close tho, less than 2 meters. i'm shocked that 90% of people are not even aware what happens if you put phone close to speakers and then you receive/send any cell data. and by "cell data", i'm not talking about wi-fi, i'm talking about cellphone network data that is on different frequency, which is why it interferes with speakers, but it doesn't damage speakers or any other equipment, its just annoying sound. headsets are not effected tho, i'm not even sure why only speakers are effected, i guess it's cuz they're MUCH more powerful than any headset. so i'm guessing it might cause that kind of annoyances on plane, but it's 0% dangerous. i'm sure that main reason is what i said, they want people to use those extremely expensive plane phones, they probably cost like 10 dollars a minute.
Back in the late 90s, cell phones could shut off your tv if you got a call. Way different bands and tech than nowadays. Bear in mind, also, that the shielding tech has gotten way better. It's why the older dial-type gauges reacted to the old band cell phones used to use, but the newer ones they tested on gave no response. It's a simple matter of 'tech improvement' leading to reconsideration of older laws.
In modern times we tell people that because they're more likely to follow the instructions the real reason is because the safety briefing is important even for experienced flyers. And in the case of a crash most likely to happen during take off and landing having everyone mental prepared to get up and get off quickly is super important. Having your phone in your hand and earphones in can greatly increase the amount of time before you brace and sometimes all you have is seconds
If they'd had a way to cut out a lot of the material and instead make a more efficient chamber for it, it would have been smaller, but the sheer volume of helium needed is just impractical. Absolutely.
probably a reason why you can't use your phone on the plane is so you don't have people disturbing others with ringing phones and hours of talking on the phone

5:30 the math is wrong.
In this case it's as simple as dividing the molar masses of each component with one another since the amount of particles (moles) in 1 L of gas is the same regardless of the type of gas used.
Hence you can calculate the ratio as such:
Ratio = M(N2)/M(He) = 28/4 = 7
Which tells us that 1 L of N2 (dinitrogen - how nitrogen bonds with itself in nature) is 7 times heavier than 1 L of Helium. Not 10 times .. 7.
Now, air is 78% N2 mixed with 21% O2 (Oxygen) where the last 1% is (roughly) Argon, a noble gas that - like Helium - does not bond with itself in nature.
Hence we can estimate the ratio a bit better:
Ratio = (M(N2)*0,78+M(O2)*0,21+M(Ar)*0,01)/M(He) = (28*0,78+32*0,21+40*0,01)/4 = 7.24
Which leads us to the conclusion that atmospheric air is approximately 7.24 times heavier than Helium.
20:00 - My hypothesis here is; the reason why the tubing goes "flaccid" and appears to lose pressure is because of the relative difference in air temperature from outside to inside. I would bet money on this being a major factor. the other reason would be that, yes, helium does leak out on plastics naturally, but with the tubing that they have chosen in the show, I would hazard that I would be negligible and that you might expect to lose 1-2% volume every 12-18 hours. this is unlike latex balloons under constant tension and hoop-stress, and mylar balloons which are much thinner and less GSM and designs for balloons in small volume party applications.
I'm fun at house parties.

I wanted to know why they were using a broadcast.
Another ace for those doing preservation work.
The look on Kari's face was priceless! "Boys are so funny!"
@8:51 where the commentator says "the more helium you have the more air it displaces and the greater the lift" that is not true, if it was the case then the gas bottle it comes in would be floating away.
It's about volume displacement. As you inflate a normal latex balloon, the greater the pressure is needed to expand that balloon, the more helium you add will only make it heavier as the pressure builds inside, that's why weather balloons are made out of a thinner, more expanding material.
Yeap you want ideally not go over 1 bar.
Watching this when there's a helium shortage hits different

One advantage they had with the lead balloon is that lead, even when extremely thin is so dense that it doesn't allow any gasses to pass through. Lead is one of the most non-porious things we have.
Good old Gsm network when you could hear on the radio when you were about to receive a call.
Interstingly, the "cellphones cause airplanes to crash" myth has actual validity in the present days. 5G services in America operate close to the frequency band used by radar altimeters (3.7-4.0 GHz and 4.2-4.4 GHz respectively), which may cause the above-ground altitude reading to become unreliable. That instrument is primarily used during landing, which sounds bad, but the worst that can happen (assuming a competent flight crew) is a go-around if the pilot can't stabilize the approach. The FAA has certified most aircraft to be safe from this interference, though. Flying within a 5G tower's range is far less risky than being a Boeing whistleblower (0:2 fatalities).
European 5G towers don't have this effect because they operate on a lower frequency band of around 3.4-3.8 GHz.
Thing is the main characteristic of 5G is that it only works on shorter distances. So there's no way it'll be a problem in the air. As you pointed out the instrument that it could interfere with is something that really only gets used during landing to help with line ups. It shouldn't have much of an issue distinguishing the signals in that kind of environment.
(0:2 fatalities) killed me.
Well, not really. Not like the whistleblowers.
@@StorymasterQ just wait for the door to open mid-flight.
Or for the engine to return to ground without the plane.

31:02 polished to perfection? That's looks dirty af
phones on planes is nonsense, but i'd really like to see someone test by getting volunteers with multiple phones, put them into a big passenger plane that takes 150+ passengers, get plane ready for take off (so it's fully functionaly) and then tell volunteers to use their phones as much as they can. make calls, send texts, use gps ..etc.
if 150+ phones won't cause any interference, then nothing would.
17:15 The reason why the Hindenburg used Hydrogen and not Helium is the US government. The US were the global main supplier of Helium in those days and did not want to sell any to Hitler's Germany, so the Hindenburg had to use hydrogen, which was easy to produce.
Lucky for Myth busters there a lot of people who have tried using mobile phones in air and landed successfully.
The only thing that was busted were their clueless attempt when removing ballast, and just cutting away from one side without any awareness of balancing it and seems no straps was fitted to pull it down, so one side just raised to the ceiling and no way to pull it down.
thats a shame when they conclude "busted" for that "raft" when in wasn't and it clearly would work, as it did on paper - as the lifting power was there, and simply failed from own mistake.
Kudos for effort, but also weird they didn't use any planning when it came to the rigging for controlling it..
just as much Adam & Jamie's error for not guiding and not just Kari Byron cutting the wrong ballast 46:55
They busted the myth because there is no possible way to make a normal raft fly just by filling it with helium
@@theemptyone7650exactly!
Stupid comment
@@theemptyone7650 But they sure didn't need to build a helium balloon that just looked like a raft to prove anything.
@cejannuzi yeah,I know..but they always do that with every myth..they take it to extreme just to prove it's impossible to confirm a myth under normal circumstances
I'm surprised that they went through with the big build of the raft. Everything pointed to it failing.
if one cell phone call could take down a plane, I'm pretty damn sure they would take your cell phone away from you before you boarded.
same reason why you can't take a bomb onto a plane.
You do understand how old this show is right? Things change, technology changes. Its not so much that it would crash the plane as interfere with the electronics and instruments. I mean, if you were driving your car and your speedometer didn't work well thats not going to cause you to crash but you probably still don't want to drive like that.
@@Damaged7 Nonsense, even old planes were tested for RF interference, due to things called "lightning", which emit RF signals a million times stronger than a cell phone. (And no, an airplane is not a perfect Faraday cage - it has windows where external RF signals can get through.)
Cell phones were banned primarily because it was the perfect kind of security theater that also helped the bottom line.
@@i.m.9823 it’s about altering the signal being received and giving false information versus causing the plane to crash. As an example of sensitivity, Nickel ore cause significant compass deviations and flying around the northern edge of Lake Superior and Huron can cause, up to 15° compass variations because of the High nickel content in the ground.
The original instruments used for navigation were very sensitive. Planes needed to be tested with all equipment on, to determine how they interfered with each other. A small needle deflection due to interference can have huge consequences over 100’s to 1000’s of km’s. The instruments don’t need to go wild, in fact, that would be ideal because the pilot knows there is a problem. What’s more an issue is a small deflection that the pilot wouldn’t notice and it’s a very tiny window to cause problems. Aviation relied solely on radio frequency instruments up until about 15 years ago. Even though GPS was around before that, it was usually a supplemental tool until very recently and even today, it’s mostly classed as a secondary instrument, even though it’s practically used as primary. Pilots use both, but if there is a conflict in information, there really isn’t a way to test GPS is off, other than using instruments that rely on frequencies and because most planes have more than one frequency based instrument.
GPS has more issues than people think and the radio instruments proved to be more accurate and reliable for 50-60 years, already. That, and it took a long time to update the whole system, to start switching to gps.
Old phones were not as shielded and the regulations on which bands they could use, were not as strict/followed. They operate far more as an analog device than the digital devices we have today. The aviation industry knew for decades that other electronics can cause deviations in the instruments. With the advent of cellphones it became a concern of “We can’t be sure if that phone is safe, but we know similar devices can cause problems, so we want to to turn it off.”
Today, I’d say your phone is safe, today. I have an older plane and fly with my cellphone on, I don’t fly relying on instruments and fly by visual flight rules (VFR). Oddly, one of the biggest instrument errors I’ve seen was putting my hand up on the instrument dash, next to the floating compass, and the nickel in my ring turned the compass s about 30°. Why do you still need to turn it off? Because they want you paying attention to landing and take off and when you are in the air, you are too high and too fast to keep a signal. I fly at 4000’ and have a hard time getting a signal for more than 4-5 minutes.
Would you two like to revisit all draws or ties and redo them to get a winner? I think that would be cool with how things have changed since the show aired
Its a good thing that when you're 8km above the ground the dont get signal anyway
i really wish that show would be in metric

Helium balloons certainly exist and have done for years but they are HUGE!
Legitimately curious, what is an "analog cellphone"?

Remember when older mobile phones used to interfere with car radios and other speaker systems even switching cells cause a triple pulse you could hear
The helium raft would made more sense if they just strapped it all under a huge net and fitted a platform under the net that Adam could walk into, essentially just a hot balloon.
I was literally playing COD Warzone on my flight home from Portugal last week, still alive 😂😂
Different tech, and you no doubt used a satellite mesh network on the plane, as well. Proof positive that tech is really cool, and laws have to catch up.
It's okay, Mythbusters team. Sometimes you have days like this. Two myths with disappointing ends in the same episode. At least you got the data you needed.
FAA is very conservative organisation. If there was any case of interference between some avionics and cell-phones or even possibility of such then restrictions probably will never be canceled.
Regulations certainly don't allow them to blast their plane disturbing frequencies in the open. Unless this is more controlled than this video suggests this is up there with just pointing lasterpointers at airplanes.
Isn't that just an airship but worse?
Actually the Ramp Tester simulates only the ILS ground signals.

"the only finite resource in[sic] earth"?
_Everything_ on the earth is finite. Even sunlight is finite. It won't stop for millenia yet, but it will stop at one point.
Entropy has the final say anyway.
Fossil fuels are finite as well.
Granted I’m not thrilled about the helium useage but it’s drops in the ocean compared to military applications.
The Hindenburg wasn't designed to take helium! It wasn't a case of _craaaazy_ Fritz whimsically deciding to hook her up to the hydrogen tank instead of the helium that week(!) She was designed for hydrogen because, at the time, the States had a near monopoly on helium production and refused to allow any to be exported by law!
Iirc correctly, the real reason planes don't like cellphones is because mobile stationary stations not really like 300+ signals connecting and disconnecting around the same time due to a plane full of phones flying over.
Damn, just when was gonna start to make flying helium-raft, they say don't try this at home :/
grant was trying to call out.... the interference is supposed to be from an incoming call.
At 17:02 “..for some reason… it was filled with Hydrogen…”. From Wikipedia “Because of the Helium Act of 1925, which banned the export of scarce helium on which the US then had a production monopoly, together with the prohibitive cost of the gas, German Zeppelins were forced to use hydrogen as lifting gas, which would gain infamy in the Hindenburg disaster.” Some reason uh, you didn’t gave it to them, that’s the reason.
While a phone could not affect the plane, a 5g cell tower could
Anyone else oddly appreciating a odd sounding Jamie
25:55 he predicted that Grant would get a brain tumour

is this helium which is so light that Earth literally can't prevent it from leaving the atmosphere into space, the stuff we need to run MRI scanners? naaaa it's probably different helium right
I bet there is going to be a day when helium will be worth more than gold by volume
cellphones are not allowed on plane cuz they want you to use extremely expensive plane phone, that's all there is. if phones were so dangerous to planes, they wouldn't allow you to keep it on you while in flight. its common sense.
another common sense moment, is that cellphones output a very, very weak signal, while the towers output thousands of times more powerful signal, so if cellphone signal was dangerous to planes, then planes would fall down when they're closer than like 10km to any cell tower. cell tower sends extremely powerful cellphone signals, while phone itself doesn't even have powerful enough battery to send that powerful signal, therefore it is impossible for it to effect the plane.
i think only other reason why they tell you to turn it off or on airplane mode, is same reason as what happens when you put cellphone close to a speaker and then there's incoming/outgoing cell signal (like sending/receiving sms or calling). it has to be quite close tho, less than 2 meters.
i'm shocked that 90% of people are not even aware what happens if you put phone close to speakers and then you receive/send any cell data.
and by "cell data", i'm not talking about wi-fi, i'm talking about cellphone network data that is on different frequency, which is why it interferes with speakers, but it doesn't damage speakers or any other equipment, its just annoying sound.
headsets are not effected tho, i'm not even sure why only speakers are effected, i guess it's cuz they're MUCH more powerful than any headset.
so i'm guessing it might cause that kind of annoyances on plane, but it's 0% dangerous.
i'm sure that main reason is what i said, they want people to use those extremely expensive plane phones, they probably cost like 10 dollars a minute.
Anyone know the episode where Tory acts like a nerd (You can see it shown at @0:59 on this video)
They should do a rave under the raft
The slide to escape planes and the black box was invented in Australia 🇦🇺
Cell phones and aircraft equipment don't use the same frequency. It is not an issue.
You do understand how old this show is right?
Back in the late 90s, cell phones could shut off your tv if you got a call. Way different bands and tech than nowadays. Bear in mind, also, that the shielding tech has gotten way better. It's why the older dial-type gauges reacted to the old band cell phones used to use, but the newer ones they tested on gave no response. It's a simple matter of 'tech improvement' leading to reconsideration of older laws.
In modern times we tell people that because they're more likely to follow the instructions the real reason is because the safety briefing is important even for experienced flyers. And in the case of a crash most likely to happen during take off and landing having everyone mental prepared to get up and get off quickly is super important. Having your phone in your hand and earphones in can greatly increase the amount of time before you brace and sometimes all you have is seconds
@@thecandyman5321 If that were the case then they would confiscate books, magazines and newspapers as well.
To be fair as soon as they showed the balloons lifting a small kid... we all knew just how big a "raft" would have to be.
If they'd had a way to cut out a lot of the material and instead make a more efficient chamber for it, it would have been smaller, but the sheer volume of helium needed is just impractical. Absolutely.
26:51 This joke hits different today
let's seal a plane and use your cellphons, le's go
