 He was elected a Fellow of the Royal Aeronautical Society in July 1918 for his design work.Demobilised from the RAF, and still very sick, Porte joined the Gosport Aircraft Company in August 1919 as chief designer; it was hoped that there would be progressive developments as he agreed to use his recent patents that were very forward looking, one incorporating a ski or hydrofoil.These designs gave him the idea of lifting hydrofoils and an appointment was arranged with Lord Northcliffe who expressed an interest.
