Apart from being extremely loud as has been said Concorde had a huge turn radius compared to most other aircraft so the Compton departures from 09R saw it go a lot further east and south compared to others.
I was living in Camberley then approx 20 miles from Kingston and it was always a joy to be outside just after 7 15 -7 20 toe see it rush over the town usually rolling slightly left to take up a heading direct to Compton (in Berks just off the A34) , ideally burners still on and the low sun turning the underside a soft pink. Couldnt quite get the same enthusiasm for the triple 7 although in earlier years heavy 74 classics on a warm evening could struggle a bit climbing out of LHR on easterlies and making folks look up. as they say the past is anther country they do things differently there
