I think this must be one of Fred's ancestors - Geoffrey the Flying Bear (named after Geoffrey de Havilland).
Geoffrey was a highly experienced airbear and actually flew or rode in many historic aircraft and vehicles, including:
P-51 Mustang
P-47 Thunderbolt
Supermarine Spitfire
Messerschmitt Bf 109G
Avro Lancaster
De Havilland Devon
De Havilland Dragon Rapide biplane 'airliner'
North American Harvard
Beech 18
Josef Stalin II main battle tank
Iraqi self-propelled gun
My car
Other peoples' cars
Sadly Geoffrey is no longer with us. He baled out of a Beech 18 at 300 feet over Duxford and his home-made parachute failed to open. My fault - I made the parachute (and made him jump). Anyway, here are some archive pics of the once-legendary Geoffrey.
