The first two buildings -- a building in Madrid, as well as today's Beijing fire -- TOTALLY engulfed in flames, didn't collapse.
But the World Trade center buildings (third and fourth pictures) with a mini-fire going on, managed to collapse into their own footprint at freefall speed -- AS IF THEY WERE BROUGHT DOWN WITH CONTROLLED DEMOLITION CHARGES.
If anyone still thinks that MAYBE 9/11 was just as Fox News said it was -- you can forget about it.
It's hard to say what the TRUTH is about 9/11 -- it's much easier to say that what we've been told IS A LIE. That much is certain.
