of an aircraft. Alec published his findings with the Aeronautical Research Council. In 1936 he went to the Aerodynamics Department of the Royal Aircraft Establishment at Farnborough, Hampshire. There he became a member of the Civil Service and was able to marry his sweetheart Dora. They were to have two sons, Robert and Jonathan. Minimization of drag was his focus, even measuring drag of rivet heads, lap joints, gaps and paint. He was able to give corrective instructions for the Hampden bomber and some trainers. In 1942 he began to work with wind tunnels and

. In 1966 he became Vice-Principal at the College. His research following up the causes of the tragic Munich air crash of 1958, which resulted in the deaths of most of the Manchester United football team, was of great interest to the media, because in pinpointing the slush on the runway as the key factor, rather than the ice on the wings, the pilot of the aircraft was vindicated and the airport authorities were seen to be at fault in giving the go-ahead for take-off. Dora Young developed a brain tumor in 1968 and died in 1970. The following year daughter Judith married Herman Waldmann. His mother, a widow, then married Alec the widower. He formally retired in 1978 but continued to be very active academically with some collaborations on the research front, with consultancy both in the UK and abroad, guest lectures and the authorship of articles and several books. He was awarded an OBE in 1964, and elected a Fellow of the
