Louis Edward Curdes (November 2, 1919 – February 5, 1995) was an American flying ace of the United States Army Air Forces during World War II who held the unusual distinction of scoring an official air-to-air kill against another American Aircraft.
He was awarded the Distinguished Flying Cross twice and a Purple Heart.
He flew a North American P-51 Mustang fighter aircraft with the nickname "Bad Angel".
Curdes was one of only three American pilots to shoot down aircraft belonging to the German, Italian and Japanese air forces.
He was also involved in a bizarre incident where he intentionally shot down an American cargo plane, and then later dated one of the survivors.
In total, Curdes shot down seven German Messerschmitt Bf 109s, an Italian Macchi C.202 fighter, a Japanese Mitsubishi Ki-46 reconnaissance aircraft and an American Douglas C-47 Skytrain.
