With the beginning of the aviation age in warfare came the anti-aircraft era. In the first years of WWI opposing forces knew that aircraft would be coming but didn't quite yet know how to deal with them. Some of the results of thinking about how to stop marauding aircraft can be seen below in a few examples of patents taken from the U.S. Patent and Trademark Office. All of the following examples employed balloons--balloons that stationary and rigged in one way or another so that a passing plane that snagged this line would cause the explosive device that moored the balloon to swing up and detonate on or near the aircraft. That means that a great many of these devices were needed to be an effective deterrent against aircraft. (I had written earlier in this blog about barrage balloons proposed for use in/around London in 1938, here. This mode of anti-aircraft balloon was static, though, and at least in this circumstance the balloons were meant to snag and not necessarily try to blow up anything caught in its cable.)
Charles Francis Jenkins, the holder of the 1916 patent for an aerial mine (below), is also on the very short list of the first inventors of television:
Here's another sort of aerial torpedo, this one actually having a torpedo launched from a height with a naval target. The weapon could be charged to work against either a ship or a submarine depending on what the depth of the detonation should be.
