Design of UAV Systems • The first reported heavier-than-air, powered flight was of a UAV, over the Potomac River, by Dr. Sam Langley (1896) • The first radio-controlled UAV flights were converted Navy trainers, flown over Long Island (1917) • The first mass production of UAVs was the Kettering Bug, costing $400 and capable of carrying a 300 lb bomb (1918) • The British Queen Bee UAV was landed by dragging a weighted antenna line on the ground, which then pulled back the stick and the throttle (1935) • 4 UAVs with 2000 lb bombs attacked the Japanese merchantman, Yamazuki Maru, scoring two direct hits (1944) • Marilyn Monroe was “discovered” while working in the Radioplane OQ-3 UAV factory (1945) c 2002 LM Corporation Introduction to UAVs Amazing UAV facts Source: McDaid and Oliver, “Smart Weapons”, Barnes & Noble 1997 2-1a
