I can still remember, in the early seventies, coming over a pass into
Teesdale (I think), only to find a Vulcan flying up the valley /below/ me.
It was almost surreal to look down on that great camouflaged tin
triangle, looking like some unlikely ocean ray swimming across the
landscape. I simply had to stop and watch it till it was out of sight.

I heard a wonderful story, no idea how authentic but here goes:

One RAF Harrier squadron had a lot pilots who were also very keen
bikers, when not flying fast and low, they liked to ride the country
lanes close to base very fast. The local police heard about bikers
riding fast and started to set up speed traps. One day they pulled over
the CO for speeding. One Sunday morning a few weeks later, a policeman
was manning one of these speed traps, all of a sudden the quiet was
broken by a Harrier doing 450 knots at 40 feet directly over his head.
The speed gun was making a strange sound, flashed an error condition and
was later found to be un-repairable. The police chief constable wrote to
the squadron CO, explaining the incident and requesting payment for the
broken speed gun. The CO wrote back, saying the aircraft's threat
receiver had identified it as hostile and jammed it, the damage was
unfortunate but they wouldn't be paying for it. He finished the letter
by suggesting that to avoid further similar incidents, the police should
inform him when/where speed traps were going to be setup.
