The standards for the British science fiction comic Dan Dare, Pilot of the Future were so high that the editors hired a young Arthur C. Clarke to serve as science and plot adviser. Clarke wrote to publisher Marcus Morris in spring 1950:

I think this might amuse you. Yesterday I was lecturing at the Royal Geographical Society on the problem of interplanetary navigation … After a highly technical series of remarks, [one of the other speakers] ended up by asking ‘Will Dan Dare reach Venus?’

He did. Clarke left the job after six months — he was said to have thought that “the standard of work and research was so high that they were wasting their money getting him to check it.”
