The first production airplane of the Boeing 707 commercial jet series made its maiden flight December 20, 1957, with Pan American World Airways putting the airplane into transoceanic service October 26, 1958, and American Airlines following with transcontinental service January 25, 1959.
Concorde began commercial flight operations on 21 January 1976, with Flight BA300 from London Heathrow, UK, to Bahrain, piloted by Captain Norman Todd. The aircraft enjoyed a cruising speed of 1,350 mph (2,172 km/h), or Mach 2 â more than twice the speed of sound. Thatâs faster than the rate at which the Earth rotates, and â like Superman â faster than a speeding bullet. Unsurprisingly, Concorde halved the travel times achieved by its competitors.
