The Training of Military Pilots

Military aviation is still in its infancy. At present no one can predict the possibilities of its future. It is a vast subject, covering practically every branch of military service, and requiring every form of technical knowledge and engineering skill.

Theory of an Aeroplane Encountering Gusts

It is not proposed to indicate in any detail the mathematical methods which Professor Wilson employs in his brilliant analysis. For an understanding of these methods, long preliminary study of aeroplane stability treated in the now classical fashion of Bryan.

The Dusenberg Aero Engine

One of the largest and most powerful aero engines yet built has recently been completed at the works of the Duesenberg Motor Co., Chicago, Ill. It is the design of F. S. Duesenberg, whose success with high-speed automobile engines is well known, and who two years ago produced the pair of exceptionally powerful marine engines of the 12-cylindcr, all-in-line type, for Disturber IV.

Editorial

THE leading article on the next page of this issue, “Military Aeroplanes,” is, we believe, the most important announcement that the War Department has ever issued in regard to aeronautics in the United States Army. The officer in charge of the Aviation Section of the Signal Corps, U. S. A., says of it in a letter addressed to AVIATION AND AERONAUTICAL ENGINEERING:

IT IS REPORTED THAT—

FREDERICK T. DAVISON and, his instructor, DAVID H. McCULLOUGH, while engaged on September 8, in conjunction with the "mosquito" fleet of power craft, in the work of perfecting the new naval defence system for New York Harbor, were caught twenty-five miles outside the harbor entrance in a sudden blow that preceded a thunderstorm and narrowly escaped with their lives.

A German Hydroaeroplane

A twin-motored German hydroaeroplane, captured on April 8 in the North Sea, is the subject of an excellent article by Jean Lagorgette that has appeared in L’Aérophile. The interesting photograph shows the two German aviators taking to the water after having set fire to their machine.

Lieutenant-Colonel George O. Squier

Lieutenant-Colonel George O. Squier, in charge of Aviation in the United States Army, has been connected with aeronautics ever since 1907. In that year he drew up the specifications for an aeroplane for the United States Army, and it was these specifications with which the brothers, Orville and Wilbur Wright, complied when they delivered to the United States Army the first aeroplane any army ever owned.
