My wife’s experience may be atypical but it bears on the OP’s question and is worth retelling. She and my daughter were on board a B 707 from Beirut to London when their attention was caught by the sound of gunshots from the flight deck and the fact that the Captain was backing the aircraft away from the steps by using reverse thrust.
My wife glanced back through the curtains into the economy section as they started to taxi normally, if a little quickly, to see that everybody including the cabin crew had disappeared. She opened an overwing hatch and she and my daughter climbed with the rest of the first class passengers out onto the wing and dropped to the ground. Ground support was immediate in the form of militiamen opening fire on the aircraft as it taxied away. One passenger who was among the first out was killed when jetblast threw him against a wall. The aircraft took off with the doors and hatches open and the slides down but returned a couple of hours later, when the hi-jacker (a security guard) was escorted away by friends from his militia.
Lessons:
1.You can’t trust even a security guard.
2.When people find themselves in an unfamiliar or frightening situation they will willingly pass responsibility for their safety to anybody who appears to be in control, but they can look after themselves remarkably well if forced to.
My daughter wrote a splendid essay on “What I did on my holidays” when she went back to school and later went on to become an Air Stewardess.
