Yes, it's another book I haven't read, but that Amazon.com thinks I'd be interested in based on past purchases. Again, it was because of a textbook I bought for school. Having not read it, all I can say at this point is "sounds interesting".
Tourists in Space: A Practical Guide by Eric Seedhouse starts with a chapter that features SpaceShipOne and the Ansari X PRIZE. You can get a glimpse of this part using the "Search inside this book" feature. The book covers topics like company profiles, medical training requirements and various other aspects of humans in the space environment, survival training, vehicle orientation, and more.
If you do check it out, try getting to Amazon.com through one of the other space sites.
