NIST WTC7 Report - motion detection by subtraction

Column 79 seemingly had two conditions:
a) static vertical column
b) falling --
separated by maximally 0.16 seconds. In 0.16 seconds the column might fall 4.9 inches / 12,5 cm (free fall). The distance between wall and column 79 was 42ft (12,8m). A falling column 79 could pull the exterior wall inward - 0.02 inches (0,5mm) after 0.16 seconds.
The effect is visible. NIST saw it. ...and still believes in a much slower buckling (of the wrong column).

There is no way the column could ever 'expand' enough to tear away from all connections (The fires were not large) and the failure of one column would not collapse the building as the load is easily handled by all the other support.2.2 seconds freefall is unexplainable without demolition and the symmetry of collapse is impossible form asymmetric damage.

Demolition is long since proven.

Well done, thanx 4 ur hard work 2 let the truth come out
