Victor and Sycamore.
Something that has bothered me for 46 years. Maybe somebody will know the answer.
At Gaydon there was a series of tests done as follows. A Victor MK 1 would go to the end of the runway and prepare to take off. A Bristol Sycamore helicopter would hover, at about 50 feet, about two thirds of the way down the runway. The Victor would accelerate up to flying speed, when the previously drooping wings would "stand to attention" ready for takeoff. Shortly after this the Victor would pass directly under the Sycamore. The Victor would land and it would all start again. Unusually, I never heard any rumours or explanation about this. I watched many such tests, while doing pre-flights on "A" Squadron Victors. Sitting in the cockpit I had a grandstand seat. I was always impressed by the courage of the two crews. It could so easily have ended in tragedy.
Come on PPRuNers, What was it for?
