You remember correctly, and if you go back and read the text above the graphic in my comment #25, you'll see that I said,
"One of my conclusions was that ' IF supplemental high VOD 'cutting charges' (as suggested by Partin, et al) were used, they (three of them) were placed at or near the third floor level,at the junctures of the three main (exterior) columns and the 3' X 5' X 200' "main header/transfer beam" that spanned the width of the building at the third floor level."
And, if you look at my graphic in #25, you'll see that is exactly where the damage that I believe could be attributed to cutting charges occurred. My main emphasis was that those locations are on the exterior of the building, not in a "basement" or deep inside the structure.
