As it was, he arrived in San Francisco without even an hour's space between him and the great Onheim Safety Device try-out. No time for any rest for himself, no time for any preliminary testing of the splendid new gyroscope plane fresh from the skids of the Wiljohn factory.

There it stood--short, fixed wings, sturdy, black-enameled body, a silvered whirl of gyroscope wings above the fuselage. The strangest looking creation for flight man had ever invented! Strange looking--yes! But if it worked, it would be man's most forward step in safe flying!
