I've heard about this possible scenario before, but I'm not finding any concrete proof (yet). I'd find it hard to believe that a pilot or co-pilot would allow a crewman to sit outside while on takeoff. Taxiing for takeoff perhaps.
Despite the risks of the slipstream, a crewman of "Rigor Mortis", a B-17F Flying Fortress (KY-B, serial number 41-24591) serving with the 366th Bomb Squadron, 305th Bomb Group,
sits exposed on the edge of the radio room hatch during take off from Chelveston airbase, England. Many Fortress aviators thought the ride exhilarating. "Rigor Mortis" was lost during the disastrous run to the ball bearing plant at Stuttgart, Germany, 06 September 1943. Among the 338 bombers dispatched, she was one of 45 Fortresses failing to return, most having run out of fuel or smothered by enemy fighters when the formations scattered due to bad weather._NARA_[JASpringer]
