Quite a coincidence! One should never underestimate the incompetence of bureaucrats, but that coincidence does suggest we should be thinking of sabotage in addition to incompetence.
Security is tight, but you never know. This could have only happened at the turnaround facility, if it did. NASA says it is revieving all repair records and investigating any discrepency, no matter how small.
I should say the commission now has that responsibility.
You're being silly.
I've seen many instances where chains of odd coincidences have contributed to problems, and hindered the solution to them. It's not bureaucrats, and it's not sabotage. It just happens. There are so many people in the chain, the odds are that something is going to happen that is, in retrospect, important to something else that happened.
