It is, of course, an aviation icon.
But Concorde almost never got off the ground following an Anglo-French row about its spelling, a new documentary reveals.
The supersonic jet was jointly manufactured by Sud Aviation, in Toulouse, and the British Aircraft Corporation, London and Bristol, under a 1962 Anglo-French treaty.
Legendary: Concorde had a take off speed of 220 knots (250mph) and a cruising speed of 1,350mph – more than twice the speed of sound
Iconic: Concorde was created under a 1962 Anglo-French treaty, but that almost collapsed after a spat between Charles de Gaulle and Harold Wilson
But the upcoming BBC documentary Concorde: A Supersonic Story reveals that the treaty was almost torn up in 1967 – in a row over how they would spell its name.
The two countries initially agreed on ‘Concord’ to show their harmony – before French President Charles de Gaulle added an ‘e’, to make the word French.
Furious PM Harold Wilson ordered the ‘e’ be removed, to revert it to the English translation and the fallout threatened to derail the entire project.
It was only in 1967 when Minister for Technology Tony Benn agreed to add the ‘e’ that the planes were finally finished in Bristol and Toulouse.
Benn smoothed over Wilson’s anger by explaining his ‘e’ actually represented ‘Excellence, England, Europe and Entente (Cordiale)’.

Tuesday night’s BBC Four documentary also uncovers how spiralling costs yet again almost prompted the UK to pull out of the deal altogether.
Concorde-expert Jonathan Glancey tells the BBC: ‘The very first discussion about Concorde took place in the late 1940s among British engineers.
‘They were dreaming of a future far from the world they actually lived in, which was a world of a bankrupt Britain and ration books.
‘And yet here were these men dreaming up this Dan Dare world! Teams of engineers from Britain and France got on very well together. They liked pushing each other.
‘That competition between the engineers and the national pride involved led to a very successful machine.’
As the two countries’ engineers were working together, both sides of workers took language lessons to help them communicate.
The governments formed a treaty over the supersonic project and agreed on the name Concorde from the French word ‘concorde’ and the English ‘concord.’
In his memoirs Tony Benn recounts how the debate over the ‘e’ created nationalist uproar.
He told how an irate Scotsman wrote to him fuming: ‘You talk about ‘E’ for England, but part of it is made in Scotland!’
Given Scotland’s contribution of providing the nose cone for the aircraft, Benn replied: ‘It was also E for Ecosse!’ (The French name for Scotland).
Concorde’s flight engineer Philip Cairns told the documentary: ‘I thought the E did the aircraft a favour. It was a nice little touch. People were working together for the betterment of the aircraft industry.’
Concorde had a maximum speed over twice the speed of sound at Mach 2.04 (1,354 mph or 2,180 kmh at cruise altitude), with seating for 92 to 128 passengers.
It first flew in 1969, but formally entered service in 1976 for the next 27 years.
It is one of only two supersonic transports to have been operated commercially; the other being the doomed Soviet-built Tupolev Tu-144, dubbed ‘Concordski’.
Concorde was retired in 2003, three years after the crash of Air France Flight 4590, in which all passengers and crew were killed.
Twenty aircraft were built, including prototypes. Air France and British Airways were the only airlines to purchase and fly them.
They were used mainly by wealthy passengers who could afford to pay a high price in exchange for Concorde’s speed and luxury service.

The original program cost estimate was £70million – but huge overruns and delays meant that the program eventually cost £1.3billion.
A BBC spokeswoman said: ‘The documentary reveals the life of the most glamorous aeroplane ever built, told by the people whose lives she touched.
‘We uncover rare footage telling the forgotten row between the governments over the spelling of Concorde.
