As you probably already know (this being posted late in the day) the CAIB report has been released.
Should make for some interesting reading…when I actually have the time to read it. Meanwhile, Rand Simberg, who is far more capable of this than I, will be posting commentary on it as he reads.
Update: I know this is a trivial observation, but in flipping through the introduction, I’m impressed with the quality of photographs chosen from STS-107. Some, including the final liftoff, the Sinai, and the Moon on Earth’s limb, are stunning.
