OK Lockstock, there's nothing on the forum that requires you to believe anything you read here. Just because something that wouldn't have happened in the AT fleet actually occurred in the rotary world (a crewman, or loadmaster, being assessed as worthy of a pilot D Cat) which led directly to that crewman being sent for the full pilot's course to confirm the STANEVAL assessment - none of this requires your belief to be true. That the officer known as D*** M***** was given that Cat by P*** C*****h****, which was followed by DM being given the pilot's course and receiving his wings, is a matter of record and does not require you to understand how such a thing could have happened. Go blissfully into your world of fairy tales and dits and don't let actual history trouble you.
ExA - in the Puma world, particularly in the 70s and early 80s, single-pilot Pumas frequently had the crewman operate in the LHS. Sqn QHIs would give training to crewmen to prepare them for the unlikely eventuality that they might have to land the beast. DM was identified as being exceptionally skilled, hence the prep for and conduct of the aforementioned STANEVAL trip. There was a world of difference between the rotary world's integration of crewmen into the cockpit and that of the AT fleet. Pre-P2 in the late 1980s, the AAC had a similar policy of training observers and air gunners (ie ATGM operators) in the basics of getting the aircraft down in the event of pilot incapacitation.
