Mid '90s, tottering out of the Old Dungeon Ghyll Hotel in the Langdales (Lakes) at chucking out time, so dark not worth opening your eyes. We heard the sound of a Hercules approaching, it flew over us (just caught the shape) down the valley & we heard it pouring on the coal at the end of the valley as it flew up & over. The crew certainly earned their corn that night.
Sorry SM, too dark to estimate the height.
In the late 80s, I guested with F Troop on a couple of occasions doing night low level, first time WITH NVG and second without . . . . err, interesting.
Yep, as far as I'm concerned they do 'earn their corn'.
Safe flight lads
