A two headed calf in Sacramento, California. The two headed calf eats from a tray. The second head grows out of the side of the natural cranium. A man points at the three horns of the calf.
Leven Lake in Cisco, California. A man fixes a dynamite pack. Explosions occur in the middle of Loch Leven Lake to kill fish. Water splashes due to the explosion. State fisheries officials then release young trout into the lake.
A film titled 'High Altitude dive and glide bombing' about means of attaining accuracy and pilot safety by carrier-based light aircraft dive bombers dropping special devices. A U.S. Navy dive bomber in flight in the United States. The aircraft rolls and dives down. A bomb impacts after being released. A massive explosion occurs (small atomic / nuclear). A mushroom cloud of smoke and dust rises up. A dive bomber in flight. The aircraft dives down and drops a bomb. An explosion occurs and billows of smoke rise up.
A film about means of attaining accuracy by dive bombers in the United States. Animation shows the trajectory path of a bomb after being released in mid air. The distance that a bomb would fall short of the target, if not compensated for, is called the "trail." A graph depicts the altitude of release of the bomb and the sight angle. Animation explains the concepts. A pilot sets a lead at a target. Animation depicts the importance of the lead at release altitude. Results are illustrated in animation. Consequences of taking a wrong flight path are explained. A graph depicts the means of computing the release altitude and the sight angle. The effect of wind on a diving aircraft as it affects the flight path.
A film about means of attaining accuracy by dive bombers in the United States. Animation depicts the importance of standard runs, at 50 and 70 degree dive angles, to improve the accuracy of bombing a target. A graph depicts the sight angle and release altitude. Wind correction tables. Animation depicts means of lead correction. A dive bomber aircraft in flight dives. A technician speaks over a wireless and looks at the aircraft in flight. Animation depicts the accuracy of half readings in bombing a target area. Smoke rises as a bomb impacts. A technician enters various details in a chart.
