NASA's abilities are judged on performance. They have just had a failure. If it turns out to be a foam problem, it is then a problem they have known about for years and may in fact have been excerbated by a polically correct decision to use an "environmentally friendly' foam.
Foam has sripped of at least 6 and maybe 8, I can't recall from the paper this morning, previous flights. If this is the problem, it is negligence in my book, but given the BBers propensity to forgive incredible incompetence, I expect the culprits(if there are some) will be promoted.
