Depressurization

Cabin pressure is lost and, since the 7 April 2024 revamp, a door can be sucked out. Walking through that opening pulls you outside until you respawn inside, which wastes time. The flight continues once everyone has a mask.

Random in cruise, or chosen with Emergency Control.

Put an oxygen mask on every passenger. On Easy and Medium, exclamation marks show who still needs one. Stay clear of the open door.
