The forgotten designs, which have been unearthed in BAE Systems' archives, include a hypersonic space-plane
capable of travelling at five times the speed of sound, a jeep that leaps over enemy blockades and a commercial aircraft able to take off and land vertically in densely populated cities.
A few years earlier, a maverick Austrian engineer named Eugen Saenger had published a paper proposing a manned, rocket-propelled space-plane that could in theory fl y anywhere in the world.
At the end of the rail, the space-plane would start climbing.
If the space-plane concept wasn't far out enough, the bomb it was carrying was out of this world.
Myhra adds that post-war analysis indicated that the space-plane would have burnt up during re-entry but this could have been overcome with thermal shielding.
Several times Ashford estimates production or development costs of a space-plane
project with rounded up or grossly estimated numbers.
London, Oct 11 (ANI): A Boeing chief has suggested that the company's mysterious unmanned space-plane, called X-37B, developed for the US Air Force, could be scaled up and modified to carry astronauts.
The company's X-37B project chief Art Grantz revealed that at least two more versions of the 9-metre long space-plane are under investigation - one of which involves adding a crew to a much-enlarged version of the space drone, New Scientist reported.
Billionaires Richard Branson and Paul Allen have signed a deal with Rutan to use the technology behind SpaceShipOne to create private space-planes
