The Concorde remains one of the most iconic aircraft ever built — a sleek, needle-nosed jet that could cruise at over twice the speed of sound. Flying at Mach 2.04 (about 1,350 mph) and altitudes around 60,000 feet, it could cross the Atlantic in just over 3 hours — half the time of a regular airliner. Developed jointly by British and French engineers in the 1960s, it was powered by four Rolls-Royce/Snecma Olympus 593 turbojet engines with afterburners — the same technology used in fighter jets.
