The British Rail flying saucer, officially known simply as space vehicle, was a proposed interplanetary spacecraft designed by Charles Osmond Frederick.
Although the proposed craft required controlled thermonuclear fusion and other futuristic technologies, a patent application was filed on behalf of British Rail in December 1970 and granted on 21 March 1973.
However, the project was revised and edited, and by the time the patent was filed had become a large passenger craft for interplanetary travel.
These magnets would accelerate subatomic particles emitted by the fusion reaction, providing lift and thrust.
