According to Jennings By Anthony Buckeridge 1955

From dust jacket: "When the space-craze sweeps through Linbury Court School, the corridors reverberate to a crescendo of Voom-voom noises , as rockets, piloted by "Butch Breakaway" Jennings, and his "bald-headed scientist, "Darbishire, take off for the moon." "Mr. Carter prophesies that the craze will wear off, and so it does-but not before Jennings has stuck his head into trouble; nor before he and Darbishire have helped General Merridew, that peppery but most distinguished of Old Boys, to recapture some of the wilder moments of his lost boyhood, to a clarion accompaniment, of bells. " Mr. Wilkins too, does his unwilling share of "ringing out wild bells", and he has never yet discovered the real reason behind Jennings' and Darbishire's insistence that boxing-gloves and frogs'-feet are unremarkable sleeping gear." The Jennings stories are so humours and this is because there is so much humour to be found in studying the reactions of the juvenile mind to the corporate life of a school.
