Krystal,
I was on 103MU at that time, same job, plus centre wing box fuel leak rectification, at least we had Keo to cool us down.
There was an article published some time after the incident with Wing Co Holden, Air Clues I think, the subsequent stress problems were caused by keeping a stiff upper lip at the time, the RAF MO reckoned that if he had let off steam at the time with a bottle of whisky he would have been ok, I'm not sure if that would be current medical advice.
It was certainly standard practice at the time that I worked on Lightnings to chain the nose leg to a ring set in the concrete on the run bay when carrying out power or reheat runs, in addition to the normal main wheel chocks.
I think that the engineering manhour/flying hour rate was something around 60 to 1 on the RAF Lightnings, so apart from the fuel bill the maintenance would cost a bomb to operate one today
Best regards,
