This http://www.fas.org/irp/mystery/nasp.htm]site gives more information about how such a thing may work in non marketing/press release talk.
I'm halfway through it and basically what I'm getting, its not possible, or rocket propelled planes are still better.

I have been looking up the problems that you encounter at hyper sonic speeds (above mach 8) a biggie is heat.
Looking at the http://www.key-to-steel.com/]key-to-steel site. Which is a paid for database containing 29.000 alloys and their properties. But there are some free articles. I found this http://www.key-to-steel.com/Articles/Art88.htm]article which states in this http://www.key-to-steel.com/Articles/im … if]graphic (as an example) that alloys tend to be more heat resistanced but also become more breakable, brittle, fragile.
So its my gues that you use something like http://en.wikipedia.org/wiki/Aerogel]aerogel or wait for space stations that are able to make better alloys in zero gravity.

Fixed topic shifting issue but it really should be merged with the other one that has bee updated as well for space plane discussion... Space Plane - Space Plane
Of course here is another small topic Falcon - Pentagon Suborbital Spaceplane should be appended as well.
