We have a winner! Quite a lot survived the Columbia crash. That is on their minds. Bad guys may precisely track reentry and dig up what they can.
There should be a 20% rule for multi-billion dollar defense contracts. For every catastrophic program failure 20% of upper management should be cashiered. That'd fix it -guaranteed.
Not really applicable to the shuttle accident, which was under controlled flight for most of it’s descent. It was no accident that the debris was in Texas, as that was the state the shuttle was attempting to land. It was well into it’s decent when the heat shield failed. In an uncontrolled descent, without heat shielding, those satellite fuel tanks will blow at a much higher altitude.
