Philip Birtles was personal assistant to John Cunningham from 1962, during the flight development programmes of the Tridents and DH 125s. They became good friends and were both trustees of the de Havilland Aircraft Museum. Like Cunningham, Birtles started an engineering apprenticeship with the de Havilland Aeronautical Technical School, and followed time as Cunningham's PA by working in aerospace marketing until the closure of Hatfield Aerodrome in 1993. Birtles have had published some 45 books on aerospace subjects, often illustrating with his own photographs.
