    Laughs in supercruise

    Concorde is a tailless aircraft design with a narrow fuselage permitting four-abreast seating for 92 to 128 passengers, an ogival delta wing, and a droop nose for landing visibility. It is powered by four Rolls-Royce/Snecma Olympus 593 turbojets with variable engine intake ramps, and reheat for take-off and acceleration to supersonic speed. Constructed from aluminium, it was the first airliner to have analogue fly-by-wire flight controls. The airliner had transatlantic range while supercruising at twice the speed of sound for 75% of the distance.[5]

    The fastest transatlantic airliner flight was from New York JFK to London Heathrow on 7 February 1996, aided by a 175 mph (282 km/h) tailwind, by the British Airways G-BOAD, in 2 hours, 52 minutes, 59 seconds from take-off to touchdown.[227] On 13 February 1985, a Concorde charter flight flew from London Heathrow to Sydney in a time of 17 hours, 3 minutes and 45 seconds, including refuelling stops.[228][229]

    Supercruise is sustained supersonic flight of a supersonic aircraft without using afterburner. Many supersonic military aircraft are not capable of supercruise and can maintain Mach 1+ flight only in short bursts with afterburners. Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled.

    Some fighter jets are capable of supercruise but only at high altitudes and in a clean configuration, so the term may imply “a significant increase in effective combat speed with a full weapons load over existing types”.[1] One of the pre-eminent military examples of supercruise is the F-22 Raptor, for which supercruise was defined as “the ability to cruise at speeds of one and a half times the speed of sound or greater without the use of afterburner for extended periods in combat configuration.”[2]

    One of the best-known examples of an aircraft capable of supercruise, and the only notable non-military example, was the Concorde. Due to its long service as a commercial airliner, the Concorde holds the record for the most time spent supersonic; more than all other western aircraft combined.[3]
