Don > most military demolition specialists, including those connected to Mossad or CIA, would be familiar with the basics

I guess so, even though this was a job presumably requiring the greatest amount of expertise and experience. Hundred floor buildings don't come by every day.

Apropos the magnitude of the explosion in each tower,
>>The Palisades seismic data recorded a 2.1 magnitude earthquake during the 10-second collapse of the South Tower at 9:59:04 and a 2.3 quake during the 8-second collapse of the North Tower at 10:28:31.

A "sharp spike of short duration" is how seismologist Thorne Lay of Univ. of California at Santa Cruz told AFP an underground explosion appears on a seismograph. Another seismologist, Won-Young Kim, stated that the Palisades seismographs register daily underground explosions from a quarry 20 miles away. These blasts are caused by 80,000 lbs. of ammonium nitrate and cause local earthquakes between Magnitude 1 and 2. <<

Extrapolation the quarry data to the WTC would indicate that an equivalent of at least 120,000lb (60 tonnes) of explosive was used in the basement of each tower and that's apart from what was used in tower itself. On the assumption that conventional explosives were used, this is a considerable amount which would have to have been brought in surreptitously, and presumably by hand. Clearly, this is not something that could have been done over a week-end.
