It was piloted by U.S. Air Force Capt. Charles E. "Chuck" Yeager who named the aircraft Glamorous Glennis in tribute to his wife... [Next "story", skipping some bits...] He reached a speed of 1127 kilometers per hour (700 miles per hour), or Mach 1.06 at an altitude of 13,000 meters (43,000 feet)." -- Voragh tlhIngan ghantoH pIn'a' Ca'Non Master of the Klingons
