Time.com has comments on the possible cause of the accident. They say that most probably the International Space Station will be evacuated somehow and then abandoned for a few years at least. Dave Winer’s Scripting News pointed at that link and posted many others.

Ernie the Attorney quotes Richard Feynman‘s thoughts on the Challenger accident:

…For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

Doc Searls‘ comments on Challenger are also worth rereading. Jim Flowers is yet another weblogger setting up a collection of links and comments on the accident.
