Explosives and CD are a hot issue and I suspect will always be with no resolution of the argument within this century.
Personally I saw no evidence of explosives exploding but I wasn't there in person and the first reports of the basement explosion are compelling but;
no explosions of a scale capable of destroying the major supporting parts of the overall structure sufficiently to bring about collapse were evident.
Also, as mentioned earlier, evidence of columns cut by explosions is lacking and thermite being very messy stuff would leave mountains of evidence.
All the rubble including the steel was taken to places like Staten Island and picked through carefully for remains of victims, personal effects, items
of value by an army of workers yet no reports of 'unusual' effects on the steel came from there but they did find enough to identify the remains of
over 300 of the victims. What I found remarkable is that the bulk of the core column sections appear to have snapped cleanly at the welds and were
virtually undamaged otherwise.
I'm still open to solid evidence of something exotic and invisible that leaves no trace and functions without blasts but so far it appears to me that
the buildings suffered terminal damage from the planes striking them and they simply fell down. The collapses weren't necessary from a terror point
of view, maybe desirable but not essential.
