I was 6 years old living in Duarte, ca playing with a football with my brother on Bradbourne Ave and we heard a loud boom. We looked north towards the mountains and saw a fireball falling from the sky. We saw this plane crash.
cool
Scary bruh
What a sighting but that would send shivers down your spine
@@margaretparol4245 it did. It was terrible 😢
@@thelords4691 i also grew up in duarte and have loved aviation growing up and still do and have been wanting to hike up to the site one of these days
i know it was meant to be a serious documentary, but when the 2 guys looked at each other and crashed the models into each other just seemed comical, actually laughed at that bit.
Ye i guess that was kinda funny lol
Did we just touch tips 😳
I like this clip. It’s the entire episode in under 4 minutes!
Discovery channel does the opposite. You get 1 hour documentary with 4 minutes worth of information.
But there’s no juicy details!
Yeah, makes it easy for simpletons to understand. Smithsonian should do a channel politics. Seems quite a few people missed a few steps in civics class.
Agree the sound 1 second before the dc 9 hit the ground was so good
@Yusuf Ghazi He said under 4 min
The intense stare down to both grabbing a model and them bumping into each other was like Saturday morning kids playing.
Aye bro watch yo jet.
Watch yo jet bro *_WATCH YO JET-_*
Comrade Charlotte not funny
Jesus Llamas yeah it is
People died here you clown go make jokes somewhere else. People today man
Cool Dark humour is a thing.

When you think of the odds of two airplanes colliding it boggles the mind. Like two people miles apart, shooting high powered rifles into the air blindly and having their bullets collide.
It's not, considering how many of them are up in air simultaneously, atleast less boggling or so.
@@atul6147
Yeah and the fact they use flight paths
Well, the bullets are plane sized
oh wow, the entire cockpit was sliced off by the F-4's wing! that's crazy!
you feel wow?? I hope next time God dont keep u inside that plane.
That happened to TWA800 but it was a different cause of how the nose broke off the body of the plane
debasish raj behera dafaq
debasish raj behera he just was surprised a wing can break through a jet.
With high speed mid-air collisions like this, any parts that come into contact are destroyed. There was another mid air collision over Brazil where the tip of the winglet on a private jet chopped the whole left wing off a 737

It’s supposed to be the light from the fire/explosion
@@Pexelated i’m pressing X so hard right now
Amazing how this was impossible to predict but after it happened such phenomenal changes were quickly made that make it so unlikely to ever happen again.
Big respect to all passengers who lose their lives just to improve the system and make ours safe.
My hat and heart goes off to all of them. Air travel has only been around for like a century while ground travel, much easier, dates back to the dawn of time.
Knowing the Smithsonian channel, I was expecting the video to end at 0:50 with, "and the tapes to prove it.". Cue outro.
So...the military crafts fly around, they crash into a jetliner and then shrug their shoulders doing their normal routine? Wow........
Do you mean the plane that flew into the airline, or the military in general?
The F-4 crashed, the radar intercept officer ejected and survived, but the pilot died.
And they military did change. They reduced the number of planes flying VFR (Visual flight rule) and required military planes to contact ATC.
Oscar Persson I still find it messed up. The Military should’ve made contact.
@@AaronDanieltenni Well yeah, they thought it would be safe to avoid collision with just visual contact, and that caused the accident. I'm just saying in no way did they ignore it afterwards.
@@AaronDanieltenni yeah...i wouldnt go blaming this on negligence when there were no protocols enforcing the rules amd keeping everyone safe back then...
@@AaronDanieltenni No, you just need someone to blame.

How did the cockpit come perfectly off???
the gash from caused by the F4 created so much stress, it began cracking around the affected area.
Pressurized cabin. Helped blow the cockpit off.
or did it?
Erik Buiten V sauce music starts
Same with how you can cut glass cleanly underwater, there is so much energy from the two planes that they sliced through before there could be enough time for the impact to be absorbed.
there was only 1 survivor of this incident, it was the F-4’s RIO, he managed to eject before the fighter hit the ground, the pilot and everyone on the DC9 werent so lucky
ironic that the one person ultimately responsible survived. clearly wasn't monitoring his radar.
@@familyhelpdeskhelpdesk270 If you had read the description, you could see the Radar is malfuntion.
Incredible that as late as the '70s all over the US military & civil airtrafic did not communicate & Mil Pilots unaware of civil airspace. A miracle there were not more collisions.
But the main cause was the pilot’s inability to see the oncoming jet because it was in a blindspot - blocked by one of the window frames
Additionally, in calculations taking in the speed and distance of the F-4 they were able to figure out how big it was in the window and it turned out it went from a speck to filling the window in a matter of a few seconds
Thanks one of best F-4 pilot the AirForce have.
This was a Marine Corps plane not Air Force.
*had
Matthew Kirk he didn’t die he ejected
*pilots
@Oscarwood2005 I don't think you can blame anyone. The fighter was damaged and flew into their path, the dc9 had no radar detection and maybe not even visual detection of the fighter before it was too late. The lack of communication brought down that plane. No one did anything wrong. It was a freak accident. As captain Picard would say, it is possible to make no mistakes and still lose.
The Air Force already have 99% of the sky for them, why do they need the other 1%?
this F4 was having issue with its oxygen tanks so they had to fly commercial airline altitude to allow oxygen in the cockpit, it also seems to be the safest distance from the ground
Of course that was a USMC F4
It wasn't the air force it clearly says navy
@@darriendove8380
It was a USMC(US Marine Corps) aircraft.
@@darriendove8380 still they are fault. That's like, "we can fly wherever we want and if you get in our way, is your fault"
_"TCAS" wants to:_
*_know your location_*
[Allow] / [Deny]
Was aviation decision makers high? Means how can they say that previously there used to be no communication happen between defence and commercial flights? Sky is meant for flying and anyone can fly. Proper control over it has to be there
Because military typically flew at altitudes above commercial altitudes
But due to there being an issue with this particular F4, if flew at commercial altitudes
@@sciencenerd6623 Altitude hardly matters when your flying coordinates are same.
@@rohangupta8208 But it does... as you can have multiple planes flying in the same location at different altitudes.
When your regulation only accounted for altitude, it matters quite a bit
Blows my mind, with all that sky, planes still manage to come together 😬
How "stealth" was born....by accident!
Military planes should ALWAYS check in with civilian ATC if they enter their airspace.
Military or not, they are an aircraft. They are taking up space in the sky
And military planes tend to be faster, tougher built, and moreaneuverable than civilian ones.
This type of separation should have *never* been the case.
We all share the same sky. And none of us are untouchable.
And that's why after this they did change the reculation ()
It’s called an f4 “phantom” for a reason
Now I understand why.
okay
I like how Air crash investigation and Smithsonian channel makes old Planes like DC9 and DC8 look modern
Why does every incident on this channel have to be recreated by the investigators? "Oh, we're pretty sure a goose flew into the jet engine, but we can't be certain that was the problem unless we fly another plane up there and throw a goose in it"
Does no one just do equations anymore?
Maths can give you predictions not confirmed results.
Hiren Patel well throwing a goose into an engine costs money, math doesnt
Equations created the radar system that they were using. Then the radar failed to work in this instance so they recreate the instance to learn why the equations failed. Makes perfect sense to me.
Equations are used to make the predictions. But they're are so many variables that the models they use make a massive amount of assumptions. So to prove that the models are valid they must be empirically tested.
This accident was in 1971 - electric calculators were new back then - and often plugged into the wall outlet. It was far easier and more accurate to fly a jet past the radar a few times than try and do all the math for radar cross section, weather, plane orientation, speed, etc.
Let's formulate the question a bit differently. How can a top military plane defend itself against A2A missile, if it can easily be shot down by a something like a flying elephant?
Apparently the fighter had several damaged systems including radar and was flying back for repair. But I just read it in the comments
Elephant or even something bigger dinosaur
Yeah, but how did the pilot not see the slower, bigger civilian plane?!
@@bobbyfeet2240 because that slower bigger aircraft was still traveling at the same relative speed of a bullet..... It went from a speck In the distance to smashing into the window in seconds
Use your brain for a bit
Because flares and countermeasures can't defend against physical projectiles?(bullets and shrapnel I mean, obviously missiles are also physical but I don't know the technical word for it)
Just an observation. I think the plane taking off at 3:16 is from runway 23 at YYZ. (Toronto Pearson) That would be Woodbine Racetrack in the background.
Where can i find the full episode??
Can anyone help??
And they apperently typed up the report in a warehouse.
When I'm the captain of the F - 4 i
Will not run left, I will go straight DOWN tho
"yo watch yout jet bro, watch your jet. WATCH YOUR JET! WATCH YOUR J......"
As humans we learn through our mistakes.
If the civilian aircraft was identified and controlled by ATC, why did the fighter did not check in with ATC? Fighter or non fighter it’s controlled airspace..
They literally explained it in the video......
In 71’ the army was not under orders to check in with ATC, so he didn’t and they didn’t know the routes of the commercial flights
It was in IMC on a VFR flight plan AND had degraded equipment.
2:00 Watch video before comment.
Radio check... How do you hear me ?
Ah... Haven't got my ears on !
Unfortunately, lives were lost . . . first ! What were/are those Generals thinking . . . theyre the only ones out there ?
All episode shown by your is superb.
Either make full videos or show them in parts.
So it becomes easy to understand what happened exactly.
Well I can help you the jet plane is having an oxygen problem which caused the pilot of the jet plane little bit dizzy(as lack of oxygen caused ) and the passenger plane was not able to see it coming either by visuals or by radar .
Those days fighter jets can't be tracked down by an aircraft radar or by civilian airport radar and thus they didn't get to know about that jet is coming in same spot where plane is and thus they collided. After this they changed the rules and now civilian airport and aircraft can detect fighter jets.
Buy it
The report leaves out bureaucracy and the chain of command’s hush 🤫 hush 🤫 culture existing in both the civilian and military hierarchies.
Pretty sure many saw the problem but ignored it all together, for the fear of retaliation, lack of effort, and such.
This is crazy
I witnessed the last seconds of flight 706 thru binoculars . The nose did not separate from the Aircraft. The aircraft circled in a steep slow counterclockwise bank until it crashed. The copilot ejected safely. The pilot could not because of a flaw in the canopy. The copilot is still alive, and rumor has it, he was a pharmacist. The f4 radar was not operational at the time
Take people to before sht Happens 😔
wait until the send that second f4 for a test and it hits another dc9
Rip
Lots of crashes involved a McDonnell Douglas :/
This looks like one of this things that was probably going to eventually happen anyway.
You can say that to cars.
Wouldn’t the f-4 have seen the plane on IT’S radar? Or was it too old of an aircraft?
The f4 is a new aircraft back in the 70s
The f4 had a damaged radar and oxygen. If it wasn’t damaged it would be well above the commercial airliner though the pilot should have seen the elephant in front of him and went down not left
It was in 1971, and radars were still being developed. And the Pilot travelling at speed in a Jet fighter is doing a lot of things as well as piloting the plane. He may have come out of a cloud, or the Airliner could have been in the sun and the Pilot could not see it.
@@BatMan-xr8gg the RIO in back is for to help watch
@@foxtrot312 True, but maybe he was busy. But I have heard that their radar was not working either. We will probably never know the real truth.
If it was impossible then how you made the documentary.
why was the title changed?
What was the title?
Ye whgat was it?
Wheres Season 21?
F-4 Phantom and the DC-9 Collision is a very bad to worse case scenario
Why did air traffic guy shake the other guys hand, as if it was a goodbye?
He was shaking the hand of the investigator who had collected the tapes and was leaving.
Because he was saying goodbye... Kind of said it yourself
The number 706 must be really unlucky
191 aswell
Why didn’t the f-4 see the civilian jet on its radar?
unfocusing when flying maybe
This is bloody rediculous.
But that same plane that got sliced in half can take down a building
Sounds like there should have been charges filed...
It's an F4...
Phantom.
not impossible to predict
they recklessly threw an unfit plane into the air
Stealth mode
Best f4 pilot ever
2:23 This part is just stupidly funny
Hahaha I was thinking that as well
That belly flop made me sick to my stomach, Jesus Christ.
radio check how to you here me
answer:Not so well
But f4 has its own radars. Why did not detect the other plane?
It was in 1971, and radars were still being developed. And the Pilot travelling at speed in a Jet fighter is doing a lot of things as well as piloting the plane. He may have come out of a cloud, or the Airliner could have been in the sun and the Pilot could not see it.
@@BatMan-xr8gg but his rio absolutely should. f4 is a 2 man crewed aircraft and the rio is responsible for monitoring the radar.
@@familyhelpdeskhelpdesk270 I am no expert and was only going off what the video said, and news reports. Cheers
If you guy ever read video description. You could clearly known the Radar is malfuntion and some more information about lack of Oxygen as it is also malfuntion or something.
All that sky and still a crash bruh
All that road and still a crash
Pretty much the same
For those who need to know what actually happened I can help you, the jet plane is having an oxygen problem which caused the pilot of the jet plane little bit dizzy(as lack of oxygen caused ) and the passenger plane was not able to see it coming either by visuals or by radar .
Those days fighter jets can't be tracked down by an aircraft radar or by civilian airport radar and thus they didn't get to know about that jet is coming in same spot where plane is and thus they collided. After this they changed the rules and now civilian airport and aircraft can detect fighter jet
RIP to those who died that day 💔😪
The F-4 was at that altitude to prevent oxygen deprivation, but the rest of your explanation was fine.
DC9 AND F4IPhantom
knife on butter behavior 🙄
What happened to the pilot that ejected
The pilot died ironically only the nav survived
@@Alucard-gt1zf Well he said the pilot "that" ejected. I think he meant the Nav as if he not know much about aviation roles.
What about tcas
TCAS wasent put into use until 1986
You mean... to this VERY day? Really? 😂
wing commander ,pylon,web.
Major false conclusion in this video: Although tangental to the cause of the accident, the speed of the F-4 was not a "cause" - the closure rate was (there was a 20kt TAS difference between the two aircraft).
lack of situational awareness by the f4 crew was the cause, their radar should have easily picked up a jet that size. the collision was easy to predict and avoid if the rio was doing their job right.
@@familyhelpdeskhelpdesk270 If you ever read the description You can clearly known their radar is malfuntion.
Also blaming other why knowing nothing doesn't make you smart.
Hopefully the F-4 pilot survived.
The pilot died, the radar officer in the f-4 was the only survivor.
TheEmeraldSkies The Pilot Died In The Crash But The Radio controller jumped out So I don't think any are lucky
One died, one survived.
Only the RIO survived.
nice voice
How to get rid of a stealth jet crash into it
better regulation after each accident and before it.
Did both of the fighter pilots survive?
Joshua Aponte only radar officer survived the other was most likely unconcious
Only one survived.
yes i think they ejected
RIO ejected and survived pilot was unable to because of a design fault that would not connect the circuit to the seat after canopy jettison if the rear ejected first this problem had been identified and fixed but that particular plane hadnt gotten the fix yet
dc-9 got mortal kombat fatalitied
Honestly how do you not see a plane coming towards you
Try to walk in their shoe and you'll see. Guess that will be your last chance too.
Hw abt a TCAS?
Not in 1971
Well the F-4 pilot could escape..
couldn't
0:02
“Radio check how do you hear me?” They don’t because they dead.
it must have been an alt that crashed into the f4
Thank god the camera crew survived
They did not die in vain.
god gave you 2 eyes use them.
The F-4 is fun.
Okay, so why didn't the Marine F4 detect the airliner? I'm _pretty sure_ that they are equipped with radar.
Radar was not required to always be on
@@Alucard-gt1zf Even on commercial aircraft, the radar is ALWAYS ON, for both weather detection and collision avoidance. I believe that they are separate systems, but both are always on.
@@craigcorson3036 doesn't mean the military needed theirs on
@@Alucard-gt1zf If it was not needed, it would not have been installed on the plane. No pilot flying a plane with radar installed would fail to use it. At the speeds those things typically fly, it would be extremely foolhardy not to use your radar; you need advance warning of the presence of other aircraft in the area. It would be like flying with a blindfold on - crazy. Suicidal.
@@craigcorson3036 someone in the comments section said that both the radar & the oxygen cylinder of the fighter jet were malfunctioning & the jet was returning to the base to have them repaired.
G.O.L 1907
well somebody didn't turn on their TCAS
this accident happened in 1971 TCAS in aircraft didn't really exist until the 80's

'plane goes off radar and controllers tell plane.toturn on transponder'. Why didn't the controller's just call an emergency straight away and not waste precious time. Some humans really are slow
The most common cause of loss of transponder is faulty transponder. Occam’s razor.
Mate, we can't just assumed that they are slow to respond. There are sets of procedure to deal in certain condition.
For example, if you have a phone call with your family, do you assume that they have an accident when they suddenly hung up the phone despite the fact that there is a chance that the battery is flat/out of juice?
That is a poor conclusion of your.
was it because the F-4 had a radar cross section too small for a civilian ATC radar to pick up?
Not really. I was a controller in that exact sector where the crash occurred (L.A. Center sector 18 / 118.55). There are two radars used there, one at LAX and the other in Boron (not Palmdale like the video says -- that's where the physical ATC building is located). The crash happened over the San Gabriel mountains sort of in-between, and raw radar coverage there has always been spotty. Because of the mountains and terrain, there are about 1,000 "primary" targets shown on the scopes at any given time, picking up a lot of cars on highways, buildings on the mountains, etc. But they'll typically twinkle on and off and not move much. To detect an aircraft among those 1,000 you have to see a solid history of targets which indicates something moving in the air (a hit every 12 seconds). If coverage is spotty you'll get a hit, then 36 seconds of nothing, then another hit so you can't tell it's a moving aircraft (looks like any of the 1,000 other targets in that case). That's why since then they require transponders on all aircraft in that area (and in other busy areas), which can be picked up much easier than raw radar only.
@@kewkabe A radar designed to pick up airplanes picked up cars?
@@Ranman242 Yes, just depends on the elevation of the highway in relation to the radar site. Radar waves don't know what they're bouncing off. The Boron site picked up about a 30 mile stretch of nearby highway 58 pretty strongly, and the LAX site picked up a lot of traffic and buildings in the San Fernando Valley area (about 600 feet higher elevation than the radar site).
Wow!
@@kewkabe how about the radar on the f4 cant they pick up the dc9
That f4 is actually a stealth variant
I hate your ending😩😩😩😩
The sad truth about America, is instead of changing potentially fatal flaws in a system. They'll wait till a disaster happens to do anything about it...
Then what are you suject for up coming disater? Can you predict it and how to prevent something we never encounted before?
