With an early scientific bent Freddy broke with family tradition and did not go into the army, even though World War Two had just begun. Instead he went to the Royal Aeronautical Establishment, Farnborough, to help in the development of radio and radar devices; he became a Boffin. As one of the top Boffins, Freddy rose to the top of his profession and was the British Scientific Advisor to America on several military projects. Such was the secrecy of some of these projects referred to here, that the manuscript for this book had to be submitted to the Ministry of Defence for clearance. During and after the war he flew tests in many military aircraft and witnessed the secret tests carried out at Farnborough, including the flights of Britain's first jet fighter. After the war, he took up flying light civilian aircraft from a local club and became an instructor with several of these clubs, including the famous Tiger Moth Club at Redhill.
