Please check out this impressive photo of two McDonnell-Douglas F-4 Phantom jet fighters from the U.S. Navy Blue Angels performing in close formation over Miramar Naval Air Station during the 1969 Air Show. The Blue Angels are known the world over for their precision flying and intricate maneuvers. Noteworthy in this performance for the Blue Angels was the first to fly supersonic jets in back-to-back formation with the top plane inverted and the second snuggled underneath right side up with minimum separation.
