HL-10 in flight after launch
The HL-10 lifting body is seen here in powered flight shortly after launch from the B-52 "Mothership". When HL-10 powered flights began on October 23, 1968, the vehicle used the same basic XLR-11 rocket engine that powered the original X-1s. A total of five powered flights were made before the HL-10 first flew supersonically on May 9, 1969, with John Manke in the pilot's seat.
