Milburn Grant "Mel" Apt (April 9, 1924 – September 27, 1956) was a U.S. Air Force test pilot, and the first man to attain speeds faster than Mach 3. He was killed after separating from the Bell X-2 in his escape capsule during the record-setting flight that exceeded Mach 3. Shortly afterwards, Secretary of the Air Force Donald A. Quarles commended Apt, saying he was "flying faster than any human being has been known to fly."
