Airship In Gunfire Test.

New York Times 100 years ago today, April 23, 1913:
Army Man, 5,000 Feet Up, Rights Machine the Vibrations Rock.
    SAN DIEGO, Cal., April 22.— Lieut. Samuel McLeary, United States Army Aviation Corps, remained in an army aeroplane over the armored cruiser Maryland to-day during target practice with 8-inch guns to test the effect of vibrations on the stability of the machine. The test was made at an altitude of 5,000 feet, and, although the machine rocked dangerously each time the guns were discharged, the aviator succeeded in righting it.
    During the firing Lieut. McLeary also tested a new range-finder device, swooping down as near the cruiser as possible after each shot and signaling to the range-finding officer the distances determined by the aid of the new device.
