Puritan Pictures, a poverty-row operation devoted in the main to Tim McCoy westerns, turned out a few diverting murder mysteries during its short life span. In Death in the Sky, Leon Ames plays a World War I ace whose combat experiences have driven him mad. Convinced that every other aviator on earth poses a personal threat to him, Ames contrives to kill anyone who pilots a plane. Only hero John Carroll and heroine Lona Andre stand in the way of Ames' murder spree. The matching of new footage with stock shots from such earlier air epics as Hell's Angels is not always convincing, but at least the film keeps on the move. ~ Hal Erickson, Rovi
