 In 1930 Inglis was appointed to the board of inquiry looking into the crash of the airship R101, and in the same year was made a Fellow of the Royal Society. He was a member of the London, Midland and Scottish Railway's Advisory Committee on Scientific Research from 1931 to 1947 and conducted numerous experiments on their behalf in the laboratories at Cambridge. He was able to prove the factors behind hunting oscillation, a violent oscillation of railway carriages, and developed testing equipment to approximate the wear of rail track and wheels in the field.
