Not quite all the work was top notch! We had a brand new Vampire T11 arrive on the line at RAF Swinderby in 1956 that everyone wanted to fly. I was lucky and got my hands on it very early on for a solo medium level aerobatics sortie. Half way through a high speed loop there was a loud bang and the plane flicked violently. I levelled off and looked out at the left wing, which was trying to drop and had changed colour from silver to green. During my return to Swinderby I had to hold up the wing, more particularly on finals to land. The aircraft was dismantled and sent to an MU and we received the result of the inquiry a few weeks later. One wing had been made at De Havilland Hatfield and the other at Broughton Cheshire. As they were different one had to be built up with filler to match the other! Normally they were in pairs, but this Vampire was not, even though it looked wonderful!
