Convair 880 and 990 are the four-engine jet airliners, developed by Convair in the late 1950s. While competing with the Boeing 707 and the Douglas DC-8, these aircraft exceeded in speed. Reaching the marks of 620 mph or 1000 km/h, these planes are still among the fastest commercial aircraft in the world, giving way only to the supersonic planes. Thanks for watching! Our Facebook:
