> At take off and during subsonic flight, 82% of the thrust is developed by the engine alone with 6% from the nozzles and 21% from the intakes
I know that the Concorde engines are powerful but 109%??!
VIKKI - I am fortunate enough to live under the flightpath so see the bird at least once a day! Unless you specifically want to see the take off or landing, try going a bit further West of LHR at about 7:00 and looking up. It goes over Bracknell at about 7:05pm.
