Any aircraft fuelled to fly the Atlantic was going to be heavy and undercarriage design was critical, as Martinsyde found to their cost.
On being discharged from the army in 1917 he moved to Britain, taking employment with the Tarrant company, and then Martinsyde, before eventually becoming chief designer at Fairey Aviation.
The Martinsyde G.100 "Elephant" and the G.102 were British fighter bomber aircraft of the First World War built by Martinsyde.
The Martin-Handasyde Scout 1 was a British biplane aircraft of the early part of the First World War built by Martin-Handasyde Limited.
As well as piloting for A.V. Roe and Martinsyde amongst others, he flew alongside early British flyers like Tommy Sopwith, Harry Hawker, Gordon Bell and Ronald Kemp.
