He was knighted in 1929.

Avro aircraft played an important part in World War II, and Avro developed some of the major air weapons of Britain’s modern air force, including the Vulcan bomber and the Blue Steel missile. In 1962 A.V. Roe Company became an integral unit of Hawker Siddeley Aviation, Ltd.
