Trans-Atlantic Flight and Meteorology*

In the foregoing discussion an attempt has been made to present in brief form a general review of average conditions both at the surface and in the free air. A knowledge of these is of interest and importance to an aviator, but should be used with caution, for average conditions seldom occur and they would scarcely ever prevail at all points along a route as great as that from America to Europe.

The Lepère Two-Seater Fighter

One of the most successful planes developed during the war is the Lepère two-seater fighter, designed and built by Capt. Georges Lepère, with a group of French associate engineers, at the plant of the Packard Motor Car Co., Detroit. It belongs to the class of two-seater fighters of the DeH-4 and Bristol type, and would seem to mark progress over both these makes.

Veneer Body Construction

The development of veneer airplane bodies of the semimonocoque type has been considerably delayed by lack of knowledge as to the best designs, materials and methods of construction, but not because of any unsuitability or insurmountable objections to this type of construction.

The successful completion, by two of the three machines forming NC Seaplane Division 1, under the command of Comdr. John H. Towers, U. S.

Army Aircraft to Fight Forest Fire

Army airplanes and captive balloons will cover portions of the National Forests of California, Arizona, New Mexico and other states this summer, to aid in detecting and suppressing forest fires. In compliance with an order from Secretary Baker directing the Air Service to co-operate with the Forest Service of the United States Department of Agriculture in this work, conferences are under way to determine where, and to what extent the air scouts will supplement the forest rangers.
