What Everyone Gets Wrong About Planes

by Panzer
(brooding music)
- Most plane doors aren't locked.
There are no keys, no sensors or passcodes to secure them.
If someone wants to pull the lever, they can.
- A man opened the emergency exit door
and forced his way off the plane.
- And yet with 40 million flights each year,
these doors are virtually never opened in flight.
So, why not?
- Your self preservation, surely.
- Common sense.
- Most people are, you know, smart enough
to not mess with that.
- The real answer relies on where planes fly.
- How high do planes fly approximately?
- 10,000 km or is that overshooting it?
- I think that's overshooting it.
I think you'd be in space.
- 25,000 km.
That's the height of a plane flying?
- Is that way too low?
- It's too much. It's too much.
Too much. Too much.
Bring it down.
- Maybe yeah, 1,000 km?
- 1,000 km, still space.
- 50,000 ft, I think.
- Yeah, some of them can go up to 43,000 ft.
- 30,000 ft.
- 38,000 ft.
- Yeah.
Why do they fly that high?
Uhh...
- I don't know. Safety, I guess.
- Probably to avoid collision with other aircraft
and if there's high mountain ranges.
- I don't know, when storms or weather hit?
- My guess is to avoid the turbulent weather.
- I think that's a decent guess.
