BBC News reports that in 1973 British Rail patented a plan for a flying saucer to be powered by "controlled thermonuclear fusion reaction". It makes the title of a BBC series set in 1973, "Life on Mars", take on a whole new meaning.
Just imagine though if British Rail had developed these saucers. One could have gone from A to B, seen the sites of the universe and had an experience literally like nothing on earth.
And the service would still have been late and strike ridden whilst the onboard sandwiches would still qualify as a new genetic lifeform.
