Airplane bomb-drop testsIn 1910, the first trials in the U.S. investigating the use of an airplane to drop bombs were conducted by pilot Glenn H. Curtiss. He dropped lead dummy bombs on 500-ft by 90-ft targets from a height of 50-ft. His aim was successful 10 times out of 14 tries. For visibility, the missiles trailed coloured streamers. The tests were observed by Admiral William Wirt Kimball at Lake Keuka, Hammondsport, New York.* |
