Prince of Dzun--
The story going around Muroc at the time was that Bob Hoover had exceeded mach one in a dive with the F86..shortly before Yeager in the X-1. Don't know if this is true or not, but was told this by Bill Bridgeman, the Douglas test pilot that flew the D558-2 later on. I personally met some of the pilots involved with flight test in those early days...it was an exciting time in Southern California.
