Hello Peter
[QUOTE][Why? They seem to work just fine, unlike e.g. the Piper door which is held by two locks and potentially much more likely to jam. To use a metaphor, all the single door planes are death traps. If you have an obese person in the front RHS, nobody is getting out in a hurry./QUOTE]
The fact of the matter is that gull wing/swing doors on aircraft, despite normally there being two of them, are dangerous in the event of a forced landing on a rough or ploughed area. If (very likely) the aircraft were to invert, I'd rather take my chances with an unlatched before impact single entry Piper door. God forbid a ditching... Forgetting the kick out 'exits' in the rear of course.
