BEA Viscount, early 1974, handling test flight, fresh out of a heavy maintenance check (Wings, tail and engines removed, I was working with the guys on the Empennage), to fly over Boscombe Downs. Remember the winds were all over the place and so was the aircraft as we left, did many stalls, (gear down, gear up) and on our return the wind blew us around quite a bit, several of the other guy's were vomiting over the newly refurbished interior, they were politely asked to clean it up. The views from those big windows were quite good, and I didn't quite believe the acceleration of those 4 Dart engines when we were leaving, alright so it was empty.
