The HL-10 Lifting Body is seen here in flight over Rogers Dry Lakebed. Like the other lifting bodies, the HL-10 made a steep descent toward the lakebed, followed by a high-speed landing. This was due to the vehicle's low lift-over-drag ratio.

The HL-10 Lifting Body is seen here in flight over Rogers Dry Lakebed. Like the other lifting bodies, the HL-10 made a steep descent toward the lakebed, followed by a high-speed landing. This was due to the vehicle’s low lift-over-drag ratio. The first 11 flights of the HL-10 were unpowered, flown to check the vehicle’s handling and stability before rocket-powered flights began using the XLR-11 rocket engine.November 18, 1969NASA Photo› HL-10 Project Description
