Behold an actual controlled demolition:
Landmark CD
Other than the building eventually ending up in a pile on the ground, do you see any similarities at all? Note the extremely bright flashes and extremely loud explosions happening right before the collapse, not hours or even minutes prior. Note how it actually collapses almost entirely within it's own footprint, it doesn't eject material from the top hundreds of feet away. Note how no surrounding buildings were damaged whatsoever.
Can you honestly say you see no difference between this and the towers collapsing?
