Captain Thomas Neville Stack CVO, AFC (1 April 1896[1] – 22 February 1949) was a 1920s test pilot, air racer and aviation pioneer.
In 1921[2] he re-joined the Royal Air Force and served in Iraq leaving in 1925 to become chief flying instructor with the Lancashire Aero Club.
[5] In 1934, to enable him to compete in the England-Australia MacRobertson Air Race, Stack together with Sidney Lewis Turner had a specially modified long-range version of the Airspeed Envoy (AS.6) built.
[7] However, an inquest into his death – conducted by a local magistrate and Royal Navy medical officer – revealed Stack had suffered an aortic aneurysm prior to being struck by the lorry.
The inquest was requested by his sons Anthony and Neville Stack, who flew to Pakistan after the local authorities alleged their father had committed suicide.
