Flying down a rainbow

Jimmy Devlin refurbishes a wrecked biplane, the Calico Peacock, earns a passenger license but struggles to find customers, and finally undertakes a risky job for an elderly prospector, Ed Weber. Weber claims a newly discovered gold strike at a remote place called Keno and offers scant payment plus promises of future reward; they agree to attempt an early landing and to stake claims before the anticipated rush. The account follows their preparations, the improvised flight and landing plans, the uncertainty of mechanical failure, and the mingled hope and pragmatism that drive men to gamble on sudden fortune.
