Willem Frederick August "Gus" Winckel (3 November 1912 – 17 August 2013) was a Dutch military officer and pilot who flew for the Royal Netherlands East Indies Air Force (ML-KNIL) in World War II. During the attack on Broome, Western Australia, on 3 March 1942, Winckel managed to land his plane full of refugees safely on the Broome airstrip just before the Japanese attack. He then dismounted the plane's machine gun and shot down one of the Japanese fighters, the only Allied "kill" during the attack.
