How far could jet aircraft advance if Britain backed Frank Whittle from 1929?
Short answerBritain might field a few jet interceptors around 1939 and make jets prominent in the 1941 aircraft generation, while retaining an early technological lead.
NotesSustained British support for Frank Whittle from 1929 could produce an early lead in turbojet development. A few interceptor aircraft around the 1939 generation are considered possible. More prominent adoption is placed in the 1941 generation. Continued investment through the Depression is the premise of this estimate.
