There were 12 pilots who flew the X-15, however, there were at least three others who might have joined those ranks of hypersonic pilots if history had unfolded just a little differently.

— Iven C. Kincheloe, Jr. —

Iven Kincheloe was originally chosen as the prime pilot of the X-15 for the US Air Force. Unfortunately, fate intervened and Kincheloe was killed in an F-104 accident on 26 Jul. 1958, less than three months before the scheduled rollout of the X-15. His backup was Robert White, who then became the new prime pilot for the US Air Force.

Kinch was an air ace in the Korean War, with 5 confirmed MiG-15 shoot downs, along with a further 6 damaged. Here he shakes hands with fellow ace Maj. James Jabara.

On 7 Sep. 1956, Kinch received the nickname of "The First of the Spacemen" when he achieved a record altitude of 126,200 feet while flying at Mach 1.7 in the Bell X-2.

Kincheloe was chosen as the prime pilot for the upcoming X-15 rocket plane research program by the US Air Force. Saga magazine ran an extensive

article about Kinch in their September 1958 issue. Due to the vagaries of publication, the article appeared after Kinch died in an F-104 accident on 26 July.

— Alvin S. White —

Al White was a North American Aviation test pilot, and served as the backup pilot to Scott Crossfield on the X-15 test program. Scott accomplished 14 flights on the rocket plane, while White accomplished zero. Crossfield once jokingly said that Al was lying in wait to break his arm so he could get the chance to fly! Scotty was protective of "his" aircraft. Al nearly lost his life in the 8 Jun. 1966 crash of the XB-70A Valkyrie.

The personification of a dashing fighter pilot. White is wearing g-pants that will keep blood from flowing away from his heart and head during high-g maneuvers.

White "flys" the X-15 simulator when it still resided at North American Aviation near Los Angeles International Airport. The simulator was nicknamed the "Iron Bird."

White represented North American and the X-15 at the World Congress of Flight in Las Vegas in April 1959. He is seen here signing autographs in front of an X-15 mockup.

— John A. Manke —

John Manke worked for NASA at the Flight Research Center as a research test pilot, flying nearly every type of lifting body, such as the M2-F3, HL-10, and X-24A and B. With his expertise as a rocket plane pilot, he was slated to join the X-15 as the 13th pilot on the program. When Mike Adams was lost on 15 Nov. 1967, the program wound down and Manke was not brought on board as originally planned.

John was the go-to guy when NASA handed out awards to employees at the Flight Reseach Center.

In the photo at left, three NASA employees receive awards and checks for suggestions. At the right side of that photo is Dave Stoddard, an Aerospace Engineering Technician from the X-15 Rocket Shop. In the right photo, Dave again receives an award from John, this time for Exceptional Service to NASA.

Scobee perished on 28 Jan. 1986 aboard the Space Shuttle Challenger, just 73 seconds into mission STS-51L. Michael Love died soon after this photo was taken during an emergency landing of an RF-4C on 1 Mar. 1976.
