Show Camera Shoots Plane, Shows Bullet's Route New York. In outward appearance, shape and weight, nn exact duplicate of the standard machine gun used on fighting planes, a recently devised motion mo-tion picture camera enables military aviators to practice all the evolutions of aerial combat in entire safety from bullets. Instead of firing bullets, the gun cameras take small photographs showing exactly where bullets would have struck. The exact time of the exposure also is registered, so that aviators practicing practic-ing "dog-fights" can determine which would have been shot down If the fights had been actual. |
