Shuttle HW and SW info

While the shuttle started burning, and the explosion is about to happen and in few seconds happened, that is finally exploded.
These three sequences instances were photographed by an air force pilot most probably by Israel Air Force and posted on web site.

I remeber the look of the photographs shows some symptoms of shuttle under full and stable flight control, but the structural integrity is vulnerable.

Now only telemetry record during that time is the only trace where any historical cause of flight control computer failure may be detected.
