In mid air the engine of the plane suddenly stalled, for no apparent reason. In a few seconds the rpm dropped to zero, and they dropped like a rock. Sorry to hear about the crash, hope they will do well. But this seems inaccurate. Small aircrafts don’t drop like a rock on engine failure, unless it’s already a stall situation, to my knowledge. Can someone clarify this?
