I flew the mighty beast for four tours, and was flying in a pretty Hemp coloured aircraft from the south side of the airfield on the date mentioned.
Not disputing any facts about the engine failure ( rare as it was ). If the co-pilot had acted as alleged i'm pretty sure we would have been given
a Flight Safety brief about it, or at least heard the scuttlebutt about 'X' being given an E Cat.
Anyway in my experience on 10 Sqn the Ground Engineer would not usually be on the flight deck but down the back enjoying a well earned cold
or hot drink and a plate of something rustled up by the Loadie. The Air Engineer, who would have hold of the throttles, would have prevented the
Co from further hazarding the aircraft, together with the Loud Shout of 'NO' from the Captain and Nav. The Air Engineer also had control of the
'Co-Pilot Control Tool' ( AKA Crash Axe ) stowed in his desk drawer!
