In 2000 I was on my way to Helsinki in a Finnair A321 at Heathrow taxying out towards 28R when looking out of the windows we realised that a Concorde was passing to the left of us. Just at that moment the ceiling screens folded down and the forward facing camera powered up, showing us the whole of the Concorde as it turned onto the runway and spooled up. The whole of the fuselage of our 'bus was rattling away, and then as the noise decreased we were cleared to line up ourselves and the screens showed rapidly receding reheat flames through a cloud of exhaust smoke. Despite being cleared to take off immediately, we were naturally left well behind, I could just see the Concorde climbing out to the west as we turned north and then east to head off across to the North Sea.
No prizes for guessing which flight I would have preferred to be on....
