Landing gear failure

The nose gear does not deploy. The first approach is aborted. The second is a belly landing. This is the crisis with a hard evacuation timer. Fire trucks are said to save the aircraft only if everyone is off in time. A slow cabin ends in an explosion.

Random, or chosen with Emergency Control as Gear Failure.

Brace everyone before the second approach. After the skid stops, open every door you can use and clear the cabin. Speed matters more than leftover service.
