Here is his response:
It's a pretty basic misconception. The seismic signal from collapse doesn't really begin until the destruction wave hits the ground. This is easily seen -- there won't be a large force transmitted into the ground until an equal and opposite force is transmitted into the collapsing material, i.e. slowing it down. As the conspiracists note, the collapse doesn't slow much as it passes through the building.
It is also no coincidence that the time for the collapse wave to reach the ground is ~ 10 seconds after initiation, ~10.5 according to BLBG. It's also preceded by large assemblies falling clear of the Tower and hitting the ground beside, which does take about 8.2 seconds -- as reported by NIST itself.
In other words, your friend on ATS has discovered nothing new, even though he thinks he has. It won't surprise me if nobody there can find his mistake.
Thanks,
Ryan Mackey

If Flight 93 was shot down by the USAF with the knowledge of the SecDef, doesn't that seem to indicate that Flt 93 was a real threat. That it was under the control of someone whose intent was unknown and presumed to be malicious?

I am sure you are aware that back during the flight testing days of the 707, the test pilot actually did a barrel roll in the 707 without a problem.

Russian Concorde? Are you sure about that?
Originally posted by ULTIMA1Yes and at the Paris airshow when the Russian Concord try to do a high G move the wings were ripped off the plane.

Well concerning the TU-144 (Concorski) they actually ran in to control problems and stalled it.
Originally posted by ULTIMA1I thought there were reports it was doing a high G move?
Originally posted by Freaky_Animal
They did, but that was after they lost it and tried to recover, (the reason for the nose down attitude)
Originally posted by ULTIMA1There are also reports that there were planted phoney wing blueprints for the Russians to steal so their version would not work.

Saying Russian Concorde is like saying Russian 747....there is no such aircraft.

I have never heard about that, but i guess that's one of the problems one can run into copying other peoples work.
Originally posted by ULTIMA1But i have seen a report that we tried to steal some of the plans for the Russian sub with the silent drive (like Red October movie)
