According to The Wall Street Journal, which acquired his military records at the time of his presidential bid, Harkin ferried damaged aircraft between repair stations in Japan and the Philippines, and ran test flights of the planes after they were fixed.
Oddly the Senator didn't cite as examples some former Presidents with military backgrounds like General George Washington and General Dwight D. Eisenhower. Must have been an oversight.
