In the '70s and '80s, I lived close to Castle Don., and these aeroplanes were a familiar sound, night and day. I seem to recall that in later years, there was a an early turn off the 09 centreline given specifically to this type on departure due to complaints from Kegworth residents.
One rumbled up the airway around midnight-ish, highly distinctive, and I'm guessing it was something out of Luton for Scotland.
I had a couple of pre-uni. summer jobs at EMA, and the ground runs on the compass base at full power were impressive, and seemed to last for hours.
My last encounter with one was when camping south west of Coventry, and one coming directly over the site on a two mile final on a still night. Goosebumps.
Utterly British, sadly missed.
