Commercial space shuttle prototypes fly through wind tunnel testing (Engadget)

A pair of companies developing their own commercial space shuttles are
presumably trying to flatten their hair after some rigorous wind tunnel
testing. First up, Blue Origin, founded by Jeff Bezos (the guy behind Amazon),
which has largely quiet on its efforts to shuttle astronauts to the
International Space Station. Its Space Vehicle setup will plump for a biconic
shape (seen above), with a flattened side and a split flap. According to Blue
Origin's president, Rob Meyerson, the shape allows greater volume than
traditional designs, but forgo the "weight penalty" of winged craft. Compared
to earlier capsules, the Space Vehicle's shape, with its fuselage flap to
generate lift, should also give it better control on re-entry to earth.

Juggling for wind tunnel time, Sierra Nevada's Dream Chaser has also been
blasted with smoke to test its own air resistance credentials. Its module
would lauch from the top of the rocket, and glide (as much as anything that
costs this much can) back to earth like NASA's own space shuttles. The Dream
Chaser is planning its first flight for this fall. You can check out its more
traditional take on the future of space travel after ...
