@@excellenceinanimation960 He's just saying that there are many gliders which could go that high but you wouldn't want to sit in them because they don't have pressurized cabins like Perlan 2 has. Perlan 2 is actually not that capable. The cabin is very heavy compared to a normal glider. Perlan 2's glide ratio is kind of average sitting at 43km distance traveled per 1km of altitude. Gliders like the infamous ETA have glide ratios of about 70. They have larger wings while being a less heavy compared to Perlan 2. In essence they are much more capable gliders but you don't want to set altitude records like these in them. You need the pressurized cabin Perlan 2 has! :)
wikipedia says their Vne is 56 knots IAS and 377 knots TAS. Looking at their screens, they appear to be much closer to their IAS limit than their TAS limit at current altitude. If my math is right (and I make no promises that it is), it appears that the IAS limit remains the relevant limit all the way up to their service ceiling of 90,000 ft
Really?! All this wonderful technology and they still use a bit of yarn held on by tape? I'm sure they did extensive testing on the yarn and tape to be sure yet would function properly at 76,000 ft. 🤣 (Time code 0:35)
You could always develop sub 10ms quick reaction yarn with vortex generator tips and led blinking string with colour changing indicator. Spend 1000 bucks Or get this yarn and tape for cheap
It's interesting to me that the yaw string as a turn coordinator was the first aircraft instrument developed solely for aircraft use. Altimeters and airspeed indicators already existed. Orville and Wilbur invented it to prevent the phenomenon they called 'well-digging'. Today it's called spinning
74.000 ft That's the realm of the U2 spyplane. In an unpowered glider. An absolute stellar achievement.
Magic --- NO MUSIC!!!
ABSOLUTELY BREATHTAKING. Probably the most inspirational thing I've seen in a glider on video. Thank you for sharing this experience.
All that high tech but still the good hundred year old yaw string :)
More cockpit videos please :)
I wish I could take a ride in glider that could go that high. Physics at its finest!
Many more gliders that wiould go that high than you'd want to be sitting in if they got there.

@@PolitischeImmunität ah I see! Air there a suit one could purchase? Also what makes the ETA infamous on a different vain of question?
Brilliant achievement, thank you for posting
2:16 Thew view! It almost looks like a commercial flight but with a twist.
damn, you know you're almost in space when you have ice building up in the interior of the cockpit
Incredible.
Such an amazing aircraft. 💙
1:50 omg this wave map is a thing of beauty!!! I wish I had a map of thermals around me like that :P
Would love to see a 360-deg camera view of this scene. Amazing stuff.
there are vids of the Garmin 360, see the perlan project page
See the other vids on the perlan page
I'm surprised the windows are not double pane to avoid the frost problem. That worked well when flew the wave in Colorado.
Not done probably for the weight savings, every gram counts in a glider.
must be cold in that cockpit
not much below freezing
What is the SkySight Wave showing us?
How close do you get to Vne at that altitude, bearing in mind the huge difference between indicated and actual airspeed?

@@MatthijsvanDuin wow 377kts TAS is incredible!!
Are there cockpit heaters onboard? I'm guessing not. Trying to limit weight? Good luck!! :-)
there is an electric heater for defrosting windows if needed
and I'm happy to reach 1100m in flight school......
What do you in the event of pressure loss in the cabin? 20Km is more or less instant death.
you answered your own question, so ...
tested to over 3 times limit pressure, drogue chute, and BRS
@@aerodyneservices what is BRS?
Another video shows they have oxygen masks like a fighter pilot.
@Bud Yeddi ballistic recovery system?
Rocket deployed parachute but wouldn't work until much lower presumably?
looks more like soaring a submarine :) Just make a picture looking upside down to emphasize the effect
und mein geliebter Bindfaden mit Tape angepappt .... herrlich in 60000ft funktioniert er problemlos .. 👍 enjoy the glide
Very cool. Congratulations. To be honest, I was hoping to see a bird fly past the window with a "meh" glance at the pilots :-)
Excellent
I want to go in one
Muy bueno...mucha suerte
Looks like space ship, not glider. Amazing!!
That´s amazing!
Wow!
does the skysight model stratospheric wave reasonably well?
yes, quite well, and skysight rep came out to make improvements
really cool but also claustrophobic. Landing with electric system failure is probably really difficult.
Szybownictwo to przygoda!A Perlan nie jest przygodą-to eksperyment.W dodatku z ogromnym ryzykiem dla pilotów.
👏👏👏
Nice video game.
At what altitude is the sky pitch black? Because it doesn't look like it is from here
IAS looks very low.
IAS 46, gs 18
