The above meeting of the Royal Aeronautical Society was held in the rooms of the Royal Society of Arts, John Street, Adelphi, W.C.2., on Thursday, November 29th, 1928.

The President : 'The technical aspects of the production of aircraft were of considerable importance because, from whatever point of view one regarded aircraft, economical and rapid production were essential. Mr. Sigrist is a Director of the Hawker Engineering Co. He was associated with Mr. Sopwith as far back as 1910 and had been intimately connected with the affairs of the Sopwith Company—particularly the technical affairs relating to design and construction. He had been responsible for the design of one of the first British machines to win the Schneider Trophy. His wide experience would enable him lo speak with special authority on the technical aspects of the production of aircraft. The Society was particularly glad to welcome Mr. Sigrist as a lecturer for the first time before them.
