I spent many years and over 4000 hrs flying V type aircraft and I cannot recall there ever having been any discussion or conversation with my rear crews concerning this issue. I gained the impression that the problem was, in the most part, hyped up by others more distant from the action. The only time it was ever referred to was on the occasion after a catastrophic engine failure on rotate in a recce Valiant which seriously affected the adjacent engine. For a significant period it was touch and go below 1000 ft, as we were jettisoning the underwing fuel, before it was possible to gain some height. At some time during this very uncertain period, my splendid AEO (a WP) said "Captain may I remind you that I removed your seat pins". Does this put things in perspective?
