The Americans and the Soviets famously scooped up Nazi rocket scientists at the end of the war, but so did the French and the British:
Known as Operation Backfire, the British program involved firing V2 rockets from the Netherlands to the edge of space before they splashed down in the North Sea. The experiment proved successful, with the missiles reportedly descending within three miles of their targets – more accurately than the Germans managed during the war.
Engineers overseeing the tests realized that von Braun had solved fundamental problems in rocketry: he had designed a sizeable engine, an advanced pump to get fuel in fast enough and a sophisticated guidance system.
“The rocket was out of this world, literally,” says Becklake who later helped restore a V2 for museum display. “It was packed full of high technology.”
Engineers at the British Interplanetary Society in London decided this technology could help them realise their dream of building a spaceship, a dream that had been considered fanciful only five years earlier. In 1946, society member, designer and artist Ralph Smith put forward a detailed proposal to adapt the V2 missile into a “man-carrying rocket.”
Smith’s Megaroc design involved enlarging and strengthening the V2’s hull, increasing the amount of fuel and replacing the one-tonne warhead with a man-carrying capsule. The rocket would not have been powerful enough to carry a person into orbit. Instead, the spaceman (and only a man was considered) would have been launched on a parabolic trajectory some 300,000 metres above the Earth.
Launched at an angle of two degrees, once in space the rocket would drop away and the segmented nose-cone would peel back to expose the capsule. Smith provided two windows in his design and suggested the space pioneer, kitted out in a high-altitude flying suit, might use his few minutes in space to carry out observations of the Earth, atmosphere and Sun. With the West squaring up to the Soviet Union, Megaroc would also have been ideal for spying on enemy territory.
After five minutes or so of weightlessness the capsule would fall back to Earth, its heatshield protecting the spaceman from harm. Parachutes would be deployed and it would float slowly to the ground. There was even a separate parachute for the rocket, intended to make the whole spacecraft reusable.
Smith worked out everything – from the exact dimensions of the rocket to the thrust of the engines and g-forces the astronaut would experience.
“The design was totally practical,” says space historian and editor of Spaceflight magazine David Baker, who has studied the Megaroc designs. “All the technology existed and it could have been achieved within three to five years.”
Baker, who was trained on V2 technology in the States and has spent most of his career as a Nasa engineer working on the Space Shuttle programme, says Megaroc was 10 years ahead of its time. “By 1951 Britain could have been routinely putting people into space on a ballistic trajectory,” he says.
The Brits were in no position to follow up on this early work though.

Canada, too, with the designs of Doctor Bull for the satellite placed into orbit with the mega-gun was feasible, and a nation such as Canada might have well been in the forefront of space exploration. But it was not to be.
