Therefore, I only published three likely sites for "cutting charges" -- at the junctions of the three failed exterior columns and the header. (The concrete at those junctures was completely missing (leaving two-foot gaps)- and the "cuts" were amazingly clean. Nothing was left there but rebar.
Yes, there was a significant explosion in the Ryder truck. But no one has yet to explain how a single air blast cleanly sliced that monstrous header beam into 40-foot sections -- and left the sections between columns totally unscathed.
Remember that several witnesses reported feeling the building shake before the big explosion. One of them had time to duck under her desk -- thinking it was an earthquake.
I agree with Trentadue that the missing portions of those tapes are what is really important.
