My Father worked for Autair when they had 3 and I managed to get a couple of flights. I remember it seemed very smooth although flew nose high.
My first trip was from Luton to Copenhagen and back in 1968. We came back empty and I spent most of the return flight sitting in the Captains seat being shown how to fly it by the F/O. My first flight deck experience at the age of 11! Doesn't happen now unfortunately.
My other trip was returning from Luxembourg the following year after a family arranged wine tasting trip to Germany. The Chief Pilot (Capt Dibley) was flying. After we landed it was taken into the hangar where they found cracks in the main u/c legs and the engineers were surprised it didn't collapse. Unfortunately GALZZ never flew again.
