"One major milestone in that history, without question, was the stunning performance of American airmen in the Gulf War of 1991. It was the first war to showcase the results of Red Flag, and it produced a curious tribute. It came from an Air Force pilot who, returning from a combat mission over Iraq, was heard to remark, "It was almost as intense as Red Flag.""
