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.
The shuttle was much lower than 200K feet. The shuttle was at 203,000 feet at the time it broke up. The reason you could see it so clearly is that it was glowing with heat as it entered the upper reaches of the atmosphere.
There were threads earlier this morning giving people in California heads up to see the Shuttle reenter. BTW, that height over Texas fits the flight profile.
