I managed to get my G1 on Sedburghs (I didn't fit into the rear of a MkIII) and take a total of 10 cadets on AEG flights before converting on to Ventures.
I remember the first cadet (Cdt Willard) had never flown in anything before and was shaking so much you could feel it through the airframe. Part of my brief to him was "No need to be frightened, that's my job". We must have found a little lift as at 10 minute duration it was also the longest AEG flight I did in a Sedurgh as Captain.
My total time on 'conventionals' was 24 hours 29 minutes in 254 launches. Was that really nearly 38 years ago?
