Balloons - In the Theatre of Operations - Dirigibles. Stabling a Dirigible on a windy day is no easy task. When the French had the station one was destroyed by being blown against the steel framework of the great canvas hangar. The hangar is seven hundred feet long and ninety feet high. It will accomodate two large ships or three small ones. A second hangar is in couse of construction. When complete, this unit of the American Naval Aviation Service will fly four dirigibles and keep up constant patrols
