My grandfather, Frederick Wildbore Collins, joined the RAF on 17 April 1919. He was 15, but had falsified his age.
He trained as a Wireless Operator, and was posted to the Northwest Frontier (Waziristan), where he took part in several operations with 5, 20 and 31 Sqns, flying Bristol Fighters and DH9As.
During this period he flew with Jim Mollison (later to become well-known as a record-breaking long distance aviator) and Philip Joubert de la Ferte, who became an Air Chief Marshal in later life.
He was one of only 200 or so personnel who were awarded the India GSM with Waziristan clasp. He left the RAF in 1927, only to rejoin in 1937 as a reservist.
