A highly decorated navigator who led some of the most dangerous bombing raids against Germany during World War II, Kay was also credited with launching the concept of the A-10 Thunderbolt, better known as the Warthog. Despite lacking the air-to-air combat ability of the F-15 Eagle and the high-tech stealth capabilities of the F-22 Raptor, the U.S. Air Force still uses the A-10 to support ground forces in close combat more than 40 years after its first flight in 1975.U.S. Air Force has used A-10 to support ground forces in close combat since 1975Retired Col.
