Jack Beaumont joined the French Air Force in his late teens, trained as a fighter pilot on Mirage 2000-5 single seaters for air-to-air combat, and was deployed in various conflicts. After being injured in a flying accident, he subsequently flew clandestine missions for French special forces and intelligence services before joining the DGSE, where he carried out clandestine operations in the field under false identities. He has since retired from the DGSE and is married with children.
