Synopsis:
Crackpot inventor Professor Wellington tries to sell airline executives on an idea to rocket travellers from coast to coast at the push of a button. When the executives laugh him off, Wellington vows to prove the viability of his plan. When he begins launching empty test rockets, they land with dead men inside.

Roy Raymond suspects murder. When a third rocket lands with airline executive Grant Darien aboard still alive, Roy believes he has solved the puzzle. He stows away on the next rocket, only to find Darien also aboard. The executive had been using the crackpot idea to eliminate his partners. Roy overcomes Darien and exposes his tricks, proving that the dead men were killed earlier, and the bodies were never aboard the rockets.
