I did a trip with Cyril Goulborn immediately after his return to flying.
We were a young, enthusiastic crew and we met in a local restaurant, keen to hear Cyril's tale of his heroic flying and how he outwitted his captors on the ground.
What we got from him, over dinner, was a long, quietly-spoken lecture about the suffering of the Palestinian people.
That night I learned that having the misfortune to be "involved", as you put it, in this sort of aviation event can be a Seriously Disturbing Experience. Cyril retired a short time afterwards.
Years later and now in the left-hand seat, whenever someone suggested to me that security checks were unnecessary, or could be shortened or circumvented, I would have a kind of flash-back to that sober evening......
....and insist on the full monty.
