I apologise for wording this incorrectly, and any confusion that may have caused. I should have written:

“Could you please explain to me, as I asked above, how the initial 0.5 seconds of descent of WTC7’s roofline at uniform velocity could possibly be consistent with collapse initiated by explosives?”

Chandler’s data and graph do not begin until well into the collapse, the first clear sign of which was the collapse of the penthouse.
