Many (and I mean many) moons when Heat was actually young (maybe 1966-1967 I went to a race meeting at Brands Hatch for the first meeting after something or other had been done to the track and to celebrate this fact there was a flypast done by a Lightening.
I remember the commentator saying "it's over Maidstone at the moment - and here it comes, doing 680 kts."
I saw the beast and followed it right up to overhead the track but funny thing, there was no noise. Then, when it had gone past the noise caught up. To call it noise perhaps wasn't totally doing it justice as after it had passed it did a wing-over and came back over the racetrack as dirty as it could get and THEN, pointed it's nose towards God, cleaned up and headed straight up.
My memory is that you didn't actually hear the noise as you became part of the noise. The whole world comprised of nothing else but ROARRRRRRRR.
Never to be forgotten. RIP all good things British with wings and a pox on all pollies.
