Bingoboy: You are very generous in your view of the motives of the passenger.
Imagine the poor pilot, struggling to pull off what appears to have been a wholly avoidable forced landing, when the passenger bales out from the front seat. Could he have got the beast down undamaged if he had not had the distraction of the passenger baling out at the moment critique? I think that had I been the pilot and if the passenger had not broken his leg as a result of his own actions, then he might have had more than a broken leg to worry about when I had finished with him!
