His main record at the Air Ministry included:

He preserved the core of the RAF at a time when even this was under threat from the Treasury. He encouraged the planning of vital new fighter aircraft such as the Hurricane and Spitfire. It was under his tutelage that radar was developed for use by the RAF. The Staff College at Cranwell was opened in the last months of his time as air minister....[But in underestimating the Luftwaffe he was] badly astray over the issue of German air strength in 1934–5."[1]
