The Mag. 2.3 event lasted 0.9 seconds, with the rest of the event lasting 8 seconds. 8 seconds for the entire building to collapse from standing to nothing???? The buildings were 1,368 ft tall. 1,368 ft in 8 seconds = 142.5 ft/sec. Acceleration due to gravity = 32 ft/sec/sec.
It would have taken 4.4 seconds to accelerate to that speed.
0 sec = 1368
1 sec = 1368-32 = 1336
2 sec = 1336-64 = 1272
3 sec = 1272-96 = 1176
4 sec = 1176-128 = 1048
5 sec = 1048-160 = 888
6 sec = 888-192 = 696
7 sec = 696-224 = 472
8 sec = 472-256 = 216
9 sec = 216-288 = -72
...and that would equate to free-fall speed for the entire structures collapse. Anyone care to mention a problem with that?
After that 8 seconds, all that was left was this:
...and you can't deny it - it was all over the TV.
