Judging by your handle you would know the trainer who had flown with Key on the Vanguard. He told me that he was a good operator but developed a nervous tic on the Trident. Key had been the union rep for the Munich disaster and had a lot of agro from many who thought he should have fought Jimmy Thain’s dismissal. I witnessed him the day b4 Staines having another stand up row in the crew room and was honestly shocked; Jerry and I were on a similar standby block but with different times as we were either brown line or similar..memory going. I was on a later airport standby that day and flew with one of the Macs who offered to off load me and take the flack from management. Iirc Key had tried something similar and been rebuffed by management as was normal then and certainly remained so for several months as I refused to fly with Wee Hugh not knowing his history.
