New SpaceShip One Photos Online
Alex Edwards writes "Scaled now have the latest photos from their last 200,000-ft. trip online.
The earth curvature on this one shows just how close they got to space."

Mt. Everest = 6 miles
Edge of Space = 75 miles.
Space Shuttle orbit ~200 miles (typical)
International Space Station = 228 miles
If I do the math correctly, the distance of the airplane from the (geometric) plane containing the cirle of the horizon is 75.4 miles, and the radius of the circle in the plane is 544 miles. So you would get a roughly equivalent view of circle on the ground that has a radius that is 7.2 times the distance of your eyes above the ground (7.2 = 544/75.4). This works out to about 39 feet for me (12 meters). So, yes, I think you could see the curvature.
A third way had been proposed by Max Faget for the "DC-3" straight-wing Shuttle proposal. The idea was to fly such a high angle of attack on reentry that one pretty much "pancaked" into the atmosphere. The straight wing approach was criticized for being unstable at hypersonic speeds, but my understanding of the idea was that by coming in belly first, the Faget orbiter was pretty much a blunt body with a cookie-cutter shape (the orbiter bottom and wings were like taking a cookier cutter to a blunt-body heat shield), and as such, it would be as stable and as controllable as an Apollo CM. The scary part of the Faget DC-3 was that having reentered the atmosphere, one had to do some kind of transition maneuver from the "full stall" reentry to start flying subsonicaly on those wings.
What is so innovative about the feathering is that they make a pancake reentry in the fashion of the "DC-3", but they have a workable way of making the transition to normal flight.
The original joke (as I heard it) was about the SR-71 requesting flight level 600. Although it emphasizes the additional altitude of Spaceship One to request FL1000 in the joke, class A airspace only goes up to FL600, so there really aren't flight levels above that. Sure, there's plenty of altitude up there, but flight levels have a specific meaning only between FL180 and FL600.

More specifically, they are there to show how the air is moving across the surface as the tail rotates. If they're doing anything besides lying flat, you've got a problem.
"Our interests are to see if we can't scale it up to something more exciting," he said.
From scaled.com, We look to the future, hopefully within ten years, when ordinary people, for the cost of a luxury cruise, can experience a rocket flight into the black sky above the earth's atmosphere, enjoy a few minutes of weightless excitement, then feel the thunderous deceleration of the aerodynamic drag on entry.

I thought I saw him say on the site somewhere he expected it to cost 5-10k per a ticket, which would get you 5 minutes of weightlessness, but I can not find that quote anymore. For some reason some of the people replying seem to think you are asking about the cost of the craft. I think the whole SpaceShip One project has been estimated to cost less than $30 Million, so mass produced it would cost less than that.
