I've been able to reproduce this bug many times in singleplayer Escalation and Confrontation by the following steps:
- Buy a Vortex and load it with 2 PAB-250s and 2 GPO-500s, all in the internal bays.
- Take off and drop the bombs.
- Land and use the munitions truck to rearm without exiting the aircraft.
- Take off again.
- Drop the PAB-250s and GPO-500s (it works in either order).
- Observe as you die, the camera gets launched far away, and sometimes the game crashes. If you bring the camera back, you will usually find no trace of the aircraft.
