The World’s Fastest Subsonic Airliner, The Convair 990A Coronado

Before Concorde defined what it meant to fly fast, there was another airliner that tried to push the speed of air travel. With outside the box engineering, the Convair 990A cruised faster than any airliner before it. The Convair 990A is still the fastest non-supersonic commercial transport to have ever been produced.
