I feel like you're making my point for me.
WTC1/2 and WTC were both controlled demoiltions, but different kinds.
WTC 1/2 started from the top up, very nontraditional. This caused a mushroom effect. after all, they had to have the collapse start where the plane crashed.
WTC7 is a standard collapse, a lot like the woodwards building you posted. Youtube some 40-60 story collapses. You'll see they're very much like WTC7, almost errily. If you look close at the WTC7 pics, you see the classic kink at the top, the jets coming from the top right, the streamers of smoke along the central columns (where more explosives would be used).

They even use the same 20-second countdown with 10-second warnings!
