Something funny I noticed was that when switching nations at specific intervals in the hanger after immediately opening the game you could get the AI planes in the hanger to crash.
The best way I found to do this was to either leave the game on Sweden to join on it or immediately go to Sweden upon opening the game. Letting the Gripen enter a steep angle but early in it’s climb. Switching nations to another (I found it works well with America) and letting the climb continue. letting the new jet fly at this angle until it is off screen. Then switching back to Sweden and watching for it to be plummeting on the right side of the hanger.
It can take some practice but this is roughly how I got this to happen consistently
I believe the reason for this is that the Gripen will climb the moment it spawns in which is fine for it but switching nations where their AI flies level will cause this new plane to level out and try to fly low at it’s set alt so switching back to Sweden at the right time causes the Gripen to be in an unrecoverable stall.
