Hodgkinson carried out training aboard the aircraft carrier in the
De Havilland Tiger Moth. He had completed some 20 hours of flying, including solo flights. On 12 May 1939 he was practising
blind flying at
RAF Gravesend, with a hood over his head. At an altitude of 800 feet his Tiger Moth struck another aircraft and plummeted to the ground. The crash killed his 28-year-old trainer, Fg Off John Fyrley Spanton, and seriously injured Hodgkinson. He was rushed to hospital, where his right leg was
amputated above the knee and his left leg below the knee. He was transferred to the
Royal Naval Hospital in
Chatham to recover. During this period he was introduced to the surgeon
Archibald McIndoe, who convinced him to have
plastic surgery on his burned face, so making him a member of McIndoe's "
Guinea Pig Club". By Christmas 1940, just over a year after his accident, he was walking on artificial limbs to such a standard that he was allowed back into the air. He subsequently joined the
Royal Naval Volunteer Reserve and went on numerous flights, including as a rear gunner on a bomber. ==Royal Air Force service==
