Kites
Kites have been around for about 2,500 years, and have been used for anythings. One of these things have been for the military. For signaling, for delivery munitions, and for observation, but lifting an observer above the field of battle, by using kite aerial photography.
Another of the things kites were used for was when Benjamin Franklin's experiment proving lightning was electricity. (Information from http://en.wikipedia.org/wiki/Kites)
