In der englischen Wikipedia zu Dan Dare:

Attention was paid to scientific plausibility, the promising young writer Arthur C. Clarke (later a science fiction luminary) acting as science and plot adviser to the first strip.

Der definitive Beleg von einer britischen Eagle-Fansite:

It was around this time that he wrote a story ‘The Fires Within’ that would later appear in Eagle, under the pseudonym Charles Willis. Arthur Clarke’s contribution to the early days of Eagle and ‘Dan Dare’, for which he was for a time scientific advisor, was marked here on the occasion of his 90th birthday. It may have been small in the overall scheme of his life, but that association is remembered affectionately and respectfully here.
