SpaceShipOne re-entry - Flight 13P



Speaking of Re-entry ain't the front of the craft a bit unprrotected
in that department?

Reentry isn't really that big a deal for an X-prize contender.
depending on the flight profile used, Maximum Mach Number would be in
teh region of Mach 5. Not an everysay occurance, but also a much mre
pleasant environment than, say, a reentry from orbit.

Think X-15 (Which was flying the same profile in 1963) rather than
Space Shuttle. There's a big difference between the two.


Agreed. A shuttle is coming in at Mach 25+ from a much higher altitude.
It basically free falls, using gravity as it's engine, not to mention its
base speed of Mach 25+ before it even starts to "fall" back towards Earth.
The frictional forces at those speeds compared to the speed that
SpaceShipOne will be flying is night and day. No comparison.
