Now you jog my memory, I believe that it was WD952 – thanks.
The Canberra was chosen because it was the best available airframe in which the Olympus could be housed. Even so, full power could not be developed in flight because the holes in the main spar through which the jet pipes had to pass could not be enlarged. The constricted throat limited the thrust to about 82%.
The first height record attempt was made on 4th May 1953, when 63,668 ft. was achieved, breaking Group Captain John Cunningham’s record in a de H Vampire by over 4200 ft. The second attempt – the one when I was in the Flight Shed – was with the more powerful Mk 102 engines on 29th August 1955, when 65,889 ft. was reached.
All this has brought one incident vividly to mind. We had removed the bomb doors so that lightened panels could be fitted and I was stood with my head in the bomb bay, removing pumps or something similar. I was working with a fitter, quite short in stature, rather bald but with a monk-like tonsure. He suddenly disappeared in a deluge of liquid falling from above. We had unlaced a flexible bag fuel tank located in the space above the bay and two other fitters, working in the dark were rolling it forward with their shoulders so that it could be removed via a hatch further forward. What we had forgotten was that there was ‘undrainable’ fuel lying in the tank, which promptly came out of a pump location. Although he was in some discomfort, he was a comical sight, but we suppressed any laughter. Into the shower with him, find him some spare overalls and the shop manager ferried him home and gave him the rest of the day off!
Only a few months after this I finished my tour of the works departments and transferred to a staff post, working as a very, very, very junior Development Engineer on Olympus engines for the Vulcan! Had to go to the Flight Shed quite frequently and chatted to the unfortunate fitter who, by now could see the funnier side of things but still blamed his mates ‘up top’ for not giving him a warning.
Happy days.
