Title : HL-10 first flight landing

Caption :

The HL-10 Lifting Body completes its first research flight with a landing on Rogers Dry Lake at Edwards AFB, California, on December 22, 1966. The HL-10 suffered from buffeting and poor control during the flight. Pilot Bruce Peterson was able to make a successful landing despite the severe problems. These were traced to airflow separation from the fins. As a result, the fins were no longer able to stabilize the vehicle. A small reshaping of the fins' leading edges cured the airflow separation, but it was not until March 15, 1968, that the second HL-10 flight occurred.
