No way this was a shoot down, not possible at that altitude and speed.
An onboard explosion or catastrophic failure would shread it like we observed.

Who are the remaining crew on the ISS and where are they from? Anybody?

The shuttle was much lower than 200K feet. The video camera used wouldnt be able to record it starting to break up at that altitude. Also, if you notice on the video furnished by TV station WFAA....the video camera's "battery" graphic was on.

Its best never to rule out anything...although those nuts on DU and their Bush conspiracy can be safely eliminated.

Two Americans, one Russian. They are due to get an unmanned resupply flight today, that is Sunday Feb. 2nd. They are good until June with no more resupply. They have a Soyoz "lifeboat" docked to the ISS, should an emergency return be required. They can of course get additional resupply flights, if we pay the Russians for them.
