The lifting-body model reached the ground much sooner than did the tow-plane because the lifting body's much lower lift-to-drag ratio gave it a much steeper gliding angle.

The M2-F1 made a good landing on Sterks' dirt strip, while the tow-plane landed unharmed in 5/5(1).

Arnold explained to io9 that this video has a frame rate of about 15 fps, so you are seeing the process about times that of real-time. More at io9, and read the scientific journal article in. The new design comprises other improvements of the HL that were developed before as part of the Orbital Space Plane (OSP) program by the NASA.

The main di- fference is that the original HL has a pure lifting body, while the upgrade has a Blended Lifting Body (BLB). This book is a selection of papers presented at the conference.
