The Arospatiale/BAC Concorde () is a Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation (later Arospatiale) and the British Aircraft Corporation (BAC).

Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million (£1.39 billion in 2020).

Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969.

The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines.

On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December.Concorde is a tailless aircraft design with a narrow fuselage permitting a 4-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 out of aluminium, it was the first airliner to have analogue fly-by-wire flight-controls.

The airliner could maintain a supercruise up to Mach 2.04 (2,167 km/h; 1,170 kn) at an altitude of 60,000 ft (18.3 km).

Delays and cost overruns increased the programme cost to £1.5-2.1 billion in 1976, (£9.44 billion-13.2 billion in 2020).

Concorde entered service on 21 January of that year with Air France from Paris-Roissy and British Airways from London Heathrow.

Transatlantic flights was the main market, to Washington Dulles from 24 May, and to New York JFK from 17 October 1977.

Air France and British Airways remained the sole customers with seven airframes each, for a total production of twenty.

Supersonic flight more than halved travel times, but sonic booms over the ground limited it to transoceanic flights only.

Its only competitor was the Tupolev Tu-144, carrying passengers from November 1977 until a May 1978 crash, while the larger and faster Boeing 2707 was cancelled in 1971.

On 25 July 2000, Air France Flight 4590 ran over debris on its take-off run and crashed with all 109 occupants and four on ground killed; the only fatal incident involving Concorde.

Commercial service was suspended until November 2001, and Concorde aircraft were retired in 2003 after 27 years of commercial operations.

Most aircraft are on display in Europe and America.

Toulouse ( too-LOOZ, French: [tuluz] (listen); Occitan: Tolosa [tuˈluzɔ]) is the prefecture of the French department of Haute-Garonne and of the larger region of Occitanie. The city is on the banks of the River Garonne, 150 kilometres (93 miles) from the Mediterranean Sea, 230 km (143 mi) from the Atlantic Ocean and 680 km (420 mi) from Paris. It is the fourth-largest city in France, with 479,553 inhabitants within its municipal boundaries (as of January 2017), after Paris, Marseille and Lyon, ahead of Nice; it has a population of 1,360,829 within its wider metropolitan area (also as of January 2017).

Toulouse is the centre of the European aerospace industry, with the headquarters of Airbus (formerly EADS), the SPOT satellite system, ATR and the Aerospace Valley. It also hosts the European headquarters of Intel and the CNES's Toulouse Space Centre (CST), the largest space centre in Europe. Thales Alenia Space, ATR, SAFRAN, Liebherr-Aerospace and Airbus Defence and Space also have a significant presence in Toulouse.

The University of Toulouse is one of the oldest in Europe (founded in 1229) and, with more than 103,000 students, it is the fourth-largest university campus in France, after the universities of Paris, Lyon and Lille.The air route between Toulouse–Blagnac and the Parisian airports is the busiest in France, transporting 3.2 million passengers in 2019. According to the rankings of L'Express and Challenges, Toulouse is the most dynamic French city.Founded by the Romans, the city was the capital of the Visigothic Kingdom in the 5th century and the capital of the province of Languedoc in the Late Middle Ages and early modern period (provinces were abolished during the French Revolution), making it the unofficial capital of the cultural region of Occitania (Southern France). It is now the capital of the Occitanie region, the second largest region in Metropolitan France.

Toulouse counts three UNESCO World Heritage Sites: the Canal du Midi (designated in 1996 and shared with other cities), and the Basilica of St. Sernin, the largest remaining Romanesque building in Europe, designated in 1998 along with the former hospital Hôtel-Dieu Saint-Jacques because of their significance to the Santiago de Compostela pilgrimage route. The city's unique architecture made of pinkish terracotta bricks has earned Toulouse the nickname La Ville Rose ("The Pink City").
