A British suspense drama. A bold but cautious former RAF pilot is testing a prototype transport plane when his engine bursts into flame. The aircraft firm is in financial diffiuclty and Jack Hawkin's pilot is feeling the strain after years of flying and an over-sensitive wife. Jettisoning the plane in favour of parachuting would almost certainly mean he loses his job too and further marital strain. It is a competently acted and skillfully directed film, if a little over-earnest. The action sequences race toward tedium in the second act but the family drama is convincing.
