The world's first commercial supersonic transport aircraft

 The Tu-144

The Tu-144 was the world's first commercial supersonic transport aircraft with its prototype's maiden flight from Zhukovsky Airport on 31 December 1968, two months before the British-French Concorde.  The Tu-144 was a product of the Tupolev Design Bureau, an OKB headed by aeronautics pioneer Aleksey Tupolev, and 16 aircraft were manufactured by the Voronezh Aircraft Production Association in Voronezh.

The Tu-144 conducted 102 commercial flights, of which only 55 carried passengers, at an average service altitude of 16,000 metres (52,000 ft) and cruised at a speed of around 2,200 kilometres per hour (1,400 mph) (Mach 2). The Tu-144 first went supersonic on 5 June 1969, four months before Concorde, and on 26 May 1970 became the world's first commercial transport to exceed Mach 2.

Reliability and developmental issues, together with repercussions of the 1973 Paris Air Show Tu-144 crash and rising fuel prices, restricted the viability of the Tu-144 for regular use. 

The Tu-144 was introduced into passenger service with Aeroflot between Moscow and Alma-Ata on 1 November 1977, but withdrawn less than seven months later after another Tu-144 crash-landed on 23 May 1978. The Tu-144 remained in commercial service as a cargo aircraft until the cancellation of the Tu-144 program in 1983. The Tu-144 was later used by the Soviet space program to train pilots of the Buran spacecraft, and by NASA for supersonic research until 1999. The Tu-144 made its final flight on 26 June 1999 and surviving aircraft were put on display across the world or into storage.
