John Billings: He Flew Allied Spies Behind Nazi Lines in WWII

From a Washington Post obit by Harrison Smith headlined “John Billings, who flew Allied spies behind Nazi lines, dies at 98”:

With Nazi troops on the defensive and World War II nearing an end, Army Air Forces pilot John Billings was enlisted for a risky operation organized by the Office of Strategic Services, the wartime precursor to the CIA. The top-secret mission would require him to fly deep behind German lines at night, avoiding enemy planes and antiaircraft guns, and drop three Allied spies over a frozen lake in the Austrian Alps, 10,000 feet above sea level.
