How the Concorde Plans Were Secretly Given To the Russians

Today is the 20th anniversary of its last flight of the supersonic Concorde aircraft. It was faster than the speed of sound, travelling at speeds of 1,350 mph (2,170 km/h).

Long-time Slashdot reader schwit1 shared an article from the Telegraph:
As the space race raged and dominated headlines, the U.S. and the Soviet Union were equally competitive about being the first post-war superpower to create a commercial jetliner that could travel faster than the speed of sound.' Both started work on secret projects, at the same time that Britain and France — who were less hell-bent on imprinting their superiority on geopolitics, but blessed with many of the world's finest engineering minds — were in pursuit of the same goal.

It has been known for decades that the three-horse race wasn't run entirely fairly. While the Americans, with their colossal and largely pointless Boeing 2707, never got close to getting airborne (they scrapped the project in 1971), the Soviet-built Tupolev Tu-144 won the race in 1968. When it did, though, its design similarities to Concorde appeared to confirm suspicions that the blueprints might have been leaked by espionage. In the late 1990s, it was revealed that an aeronautical engineer codenamed Agent Ace was one such spy. Recruited in 1967, he allegedly handed over some 90,000 pages of detailed technical specifications on new aircraft — including Concorde, the Super VC-10 and Lockheed L-1011 — to the KGB, the foreign intelligence and domestic security agency of the Soviet Union.
The identity of Agent Ace is revealed in Concorde: The Race for Supersonic, a new two-part documentary by the UK public broadcasting station Channel 4.

The Telegraph adds:
With the rich benefit of hindsight, John Britton isn't entirely surprised there was a Soviet mole in the factory. It was a long time ago, 1965, but something — or someone — at Filton Aerodrome seemed fishy. 'We had dozens, maybe hundreds of people working on the project, and we didn't have enough permanent staff so we took on contractors, all sorts of characters,' Britton says. At the time he was a 19-year-old apprentice engineer, working for British Aeroplane Company (BAC) in the design office for a supersonic, passenger-carrying aircraft. An aircraft that would, ideally, fly before the Soviet Union's competing effort did.
'There was one chap working there... He used to stay behind, he'd do a lot of overtime in the drawing library, taking prints off the microfilms of designs...' Britton, who is now 76, initially assumed the man — he thinks his name was George — was merely conscientious and needed copies for his work. He can titter at the memory now. 'It was only afterwards, when the Soviet aircraft came out and it looked remarkably like Concorde, when we thought... 'Ah'.'
