Concorde's name reflects the development agreement between the United Kingdom and France. Continue reading for more.

The aircraft used reheat (afterburners) at takeoff and to pass through the upper transonic regime and to supersonic speeds, between Mach 0.95 and Mach 1.7. The afterburners were switched off at all other times. Due to jet engines being highly inefficient at low speeds, Concorde burned two tonnes of fuel (almost 2% of the maximum fuel load) taxiing to the runway. Fuel used is Jet A-1. Due to the high power produced even with the engines at idle, only the two outer engines were run after landing for easier taxiing.
