You posted this within an hour or so of the accident. I just posted a link on Redstate.COM to this thread as part of a discussion of the Challenger accident and related incidents. My exact comment was:
(this) is one of the most incredible and important documents ever put on the web. Live posts told the tale, minute by minute. Minutes before the news media broke in people were posting things that let you know this wasn't likely to end well. Live links to the weather radar (for God's sake) actually showed the debris field as it happened.
I had forgotten your post and that you had nailed the cause of this tragedy so precisely within minutes.
I repeat, this is one of the most important documents ever put on the web.
And the world changed, again.
