DISCLAIMER – I am not planning on smashing the window on an airplane.
At what point in time? If the aircraft is still on the ground, it wouldn’t take off in that condition, i.e. you would be ordered to leave it again and need to take a different one. The explanation by @NeoNachtwaechter@lemmy.world is, I think, correct for what would happen if that happened during the flight.
At what point in time? If the aircraft is still on the ground
As I said, assuming a height of 30.000
I admit that I don’t know if there’s any airports where the ground is at that height… ;-)
I was replying to OP, not you. OP didn’t specify this.
Well – is it technically a flight if the airplane is still on ground?
Depends on why it is on the ground and if flight plans have been submitted etc
