In 1917, Dr. Peter Cooper and Elmer A. Sperry invented the automatic gyroscopic
stabilizer, which helps to keep an aircraft flying straight and level. Cooper
and Sperry used their technological breakthrough to convert a U.S. Navy Curtiss
N-9 trainer aircraft into the first radio-controlled UAV. The Sperry Aerial
Torpedo flew 50 miles carrying a 300-pound bomb in several test flights, but it
never saw combat.
