The development of aircraft during the war was such that a new and reliable means of transport had come into existence before the Armistice was signed. It possessed the supreme advantage of greater speed than any other form of public transport, although the commercial possibilities of the new service had still to be proved.

A committee was formed under the chairmanship of Sir Frederick Sykes, and as a result of a series of meetings held during March and April, 1919, framed the first Air Navigation Regulations and the directions issued thereunder, which became a part of the law of the land on April 30th, 1919.

In this paper I propose to deal with the sections of the regulations and directions concerning ground engineers.
