Best thread on PPRUNE. Not surprised it's generated over a million viewings.
2 memories of Luton, for which sadly, I have no photographs. Back in the early 80's ('80, '81 or possibly'82) as a BY F/O, landed from a trooper to see, on one occasion a french registered Aero Commander, with 2 underslung, pylon mounted fan engines. On another, the BAE Mosquito, HT-E. Both were parked on the Ponderosa.
Back in those days (when such things were possible!) Hoof Proudfoot and I walked across from stands2/3 (outside what was then the Britannia hangar) to have a closer look at the Mosquito and had the chance to climb up into the cockpit.
Magic moments.
