Two or three posts to this blog regarding STS-117 seem to have vanished. Given the intense security surrounding this launch (such as the 50-nm radius TFR), I am currently wondering if this was a simple mistake, server glitch, or something far more intentional.
The posts were straight relays of official press information from the KSC Public Affairs Office, as sent out on their public mailing list. They were obviously carefully vetted and cleared for publication. I don't know why they would go away.
[UPDATE: The posts turned up on another blog. I didn't post them there, but that's where they went. Looks like software weirdness, not any kind of censorship.]
