The things I remember most having worked on them was a rotation take off on exercise from the end of the runway, 4 Olympus engines all starting and cross feeding to start the other 12 engines on the 4 aircraft and then taking off one after the other, I swear the concrete was vibrating and then we squatted behind the generators as they left the apron onto the main runway, the worst thing was the intake checks on a winters morning with the wind howling across the airfield, there were 4 pans in an H section and we had to pull the giraffe from one kite to the next, fueling was easy, we connected a bowser up then went and sat in the cockpit opening the front tanks first and working back so the kite didn't sit on its ass, there were 7 tanks on either side and meanwhile outside another 5 bowsers would turn up replenishing the first one, some 40 tons of fuel taking the total weight of the aircraft to 120 tons on take-off..
