Mending a bike outside my brother's house near Southampton in August '77 (same week that Elvis died I recall) rumble of radials foretold the appearance of a DC-3 - Wrong! A Cat complete with magnetometer or whatever sticking out of its backside bimbled over extremely low. Beautiful... later seen at Gatwick apparently and these days in the USAF Museum. Funnily enough, did I but know it, the Antilles Air Boat Sandringham was visiting Southampton at the time and i did glimpse a far off view of a red finned aircraft trundling along in the distance... didn't ID it at the time but caught up with both some years later...
