Were all VC10s and SV10s built at Weybridge/Brooklands or just some? Presumably they were then flown with ultra minimum fuel to Wisley just five miles away as crow but not a VC10 flies , (probaly at least 30 miles by airliner) for the flight test programmes aside of course from heavy weight T/O hot and high etc. Of course as we all know and indeed love the fact that the VC10 was probably the loudest airliner ever made on the outside and with the short runways at both fields they created a huge amount of noise in very very Nimbyish areas -St Georges Hill for example is in between the two locations.
I was lucky enough to see the first VC10 landing at LHR and a very fine sight it was too especially with that weird low whine it made when taxying
