Nobody knows how to make a ballistic parachute that will handle a passenger jet, especially not a widebody A330. Airplane doors CANNOT be opened in flight unless you depressurize the airplane first. Even then, it would probably be difficult. The only airliner (that I am aware of) that could have the rear stairs opened in flight was the 727, which was "fixed" after D.B. Cooper took that way out. (Odds are pretty good he didn't make it, either.) http://en.wikipedia.org/wiki/Cooper_vane http://en.wikipedia.org/wiki/Cooper_vane
