HotDog referenced a particularly nasty accident, and as I was to start 707 training shortly thereafter at PanAmerican, emergency checklists were changed at PanAm, to ensure that the proper procedures were carried out by the FD crew.
The FAA saw to it that every new pilot to the type was aware, and FAA inspectors thereafter were especially vigilent about the correct drills to be carried out...and I still have the lumps to prove it
