AIRCRAFT WILL WREAK UNTOLD HORRORS IN WAR

Colonel Lawrence La Tourette Driggs, first president of the American Flying Club and one of the foremost authorities on aviation in the United States, will speak on "Our Mastery of the Air" in the Living Room of the Harvard Union at 7.30 o'clock tonight.

Is Author of Four Books

Colonel Driggs is the author of four books on aviation. One of them, "Fighting the Flying Circus", was written in conjunction with Edward Rickenbacker, the American ace, and narrates the experiences of the American aviators during the war. Tonight, a number of government films showing scenes taken in 1916 and 1918 will reveal this stage of flying development. In addition, photographic slides and films taken by Colonel Driggs himself will be used to illustrate his talk.

The colonel is credited with saying that "aircraft will one day maintain the peace of the world." He will show tonight the possibilities opened up by aviation for a war of obliteration.

Was Aviation Expert in War

A graduate of the University of Michigan and of the New York Law School, Colonel Driggs has been an expert aviator since 1909 and during the war served as aviation expert for the Allied aircraft. He has followed the development of flying closely since that time and was referred to last year by former General William Mitchell as the leading authority on aircraft in the country.
