Officials at Edwards Air Force Base in California, commemorated the 40th anniversary of the first F-15 flight recently.

July 27, 1972 marked the first time the legendary jet took to the skies. The F-15A was first, followed by the twin-seater F-15B in 1973. The more contemporary F-15C/D entered services in 1979.

As we have written, the F-15 is one of the most successful fighter aircraft in history with 104 kills and no air combat losses.
