Here’s one showing the mission profile of the basic HL-20-derived “Dream Chaser” lifting body spacecraft:
Since Sierra Nevada didn’t win one of the big commercial crew transport contracts from NASA, I don’t really know here they stand on developing the manned vehicle. But they are also advertising a somewhat smaller unmanned vehicle for cargo delivery to/from the ISS. I admit to being confounded by this. What cargo is there that’s in need of coming *down* that would merit the development of a new reusable spacecraft?
