WILSON DIRECTS AIR MANEUVERS BY RADIOPHONE
Army Airplanes Several Miles Away Dive and Loop and Wheel Under Orders From President at White House.
WASHINGTON (AP)--Through radio telephone installed on the south portico of the White House, President Wilson Friday directed the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. Mrs. Wilson and George Creel, chairman of the committee on public information, were the spectators, with a group of army officers, who conducted the installation of the aerial connected with a small field switchboard at which the president stood.
The planes in formation nose-dived several times and swung around a circle 1500 to 2000 feet above the ground. They were scarcely visible.
Several telephone receivers were connected to the switchboard and Mrs. Wilson and other members of the party were enabled to listen to the command as well as watch the execution.
Airplane Follows Orders.
A single plane carrying a flight commander rose in the air first and flew up and down, dived and looped in accordance with the telephoned directions from the ground. Then following directions the flight commander flew back to Bolling field and in response to orders called upon his squadron to maneuver.
The telephpne as used Friday was adjusted for three to five or six miles. It is similar to the instruments used by American aviators in France, the secret of which was disclosed after the armistice was signed.
Col. C. C. Culver is credited in the department of military aeronautic with having been the active agent in the development in the device.
"It was in August, 1910, that I first became interested in the possibility of sending messages from airplanes," Col. Culver said Friday, "and commenced a series of experiments which were so far successful that in August, 1916, I was enabled to send a radio telegraph message from a plane over Chatsworth, Cal., to San Diego, a distance of miles.
Forces in France Equipped.
"In February, 1917, after we had enlisted the assistance of the foremost American telephone companies and their expert acoustical men, we succeeded in transmitting vocal messages from a plane to the ground. In October, 1917, I took the first sets to France and made demonstrations there. By August 200 complete sets had been sent to our forces In France and our whole efforts was being devoted to the complete utilization of the possibilities in the offensive we expected next spring.
"Nobody invented anything new in applying the radio telephone to military airplanes. What was done was the adaptation and adjustment of previously discovered laws to a new field."
Only squad and flight leaders have their planes equipped with transmitters, so that they may give orders, as a power plant is required to generate current. The receiving apparatus, which is very light, can be installed on all planes. The visible portion of the radio sets resemble almost exactly the ordinary telephone receiver and transmitter. Colonel Culver predicted that the telephone would be a valuable adjunct to commercial use of airplanes.
