The story is loosely based on a real accident on 17 January 1966, when a US B-52 strategic bomber, carrying four thermonuclear bombs, collided in mid-air with KC-135 tanker plane near Palomares, Spain.

The Monthly Film Bulletin wrote: "Where previous Cliff Richard musicals (Wonderful Life [1964], Summer Holiday [1963]) had an engaging spontaneity about them, this one rollicks along with a clockwork joviality that makes no demands on anyone involved, least of all the actors.

Sidney Hayers directs at an appropriately frenetic pace, but does nothing to inject any originality into the proceedings, and even the liberally sprinkled musical numbers (quite attractive in themselves) are dully staged and feebly choreographed.

The supporting players, Robert Morley and John Le Mesurier in particular, do their best to break up the stultifying air of respectability; but the whole idea of centering a musical comedy round a mislaid nuclear bomb (based on an actual incident) seems, to say the least, a little ill-conceived.
