As I remember the RAFG event (including discussions with Alastair) there was a late aircraft swap, no A/C ARMED boards, no white tape on the Master Arm, no Telford on the front scope (normal with live loads other than QRA/Battle Flt), a weapon system that looked and sounded pretty much the same with live or sim missiles, all nicely wrapped up with a Stn Cdr decision to fly armed aircraft for training and missiles that could only be flown once fully armed (motors, fuses and warheads). No human factors in play there, then. "March the guilty bastards in..."
ISTR the published BOI report made much of the organisational errors, which may explain why the Scottish officer made possibly the most successful intercept of his career - in the admin office, preventing copies reaching the 43 Sqn crew-room, presumably in case the accident was contagious. Unfortunately he couldn't do much about all the other copies on the Stn.
