In the early '70s, I was still working at Los Angeles Center in Palmdale, Ca. It was located next to AF Plant 42, lots of experimental built there. I was driving out of the Center parking lot and just happened to see Bob Hoover doing practice in an F5. Pulled over and watched. He flew it like he did his P-51. Was great to watch and a great memory. I imagine the advanced F5 is fun to fly aggressor in. The T-38 and F5 version were an outstanding purchase by the USAF.
