The first point I agree with, it probably was just smoke escaping, but their response to Chandler's second smoking gun only focuses on the trail aspect, and not the much more damning fact that the object is falling faster than freefall, as if it was launched downwards. A much more obvious downward ejection can be seen in photographs and videos of the north tower's destruction...
You see that big piece of steel on the right hand side of the picture that's lined up with the roof of Tower 7? In certain videos of the north tower's destruction you can see that it "falls" much faster than the other falling material. The only explanation for this is that the piece had to have been launched downwards by some kind of explosive force.
Included are video clips of the ABC Balzac-Vitry demolition, used to demonstrate how a crushdown is possible. However, although the maker asserts that "Both the upper and lower sections of the buildings [sic] are disintegrated by the buildings [sic] own gravitational energy", they do not show an image of what that building looked like afterwards...
So much for "disintegrated"! Those videos don't debunk anything. In fact they actually demonstrate that a block of falling floors will slow down after colliding with lower floors. Something which Chandler and others have proved didn't happen in the case of the North tower.
As for the projectile, I'm not convinced by it either. I am however now highly intrigued by this missile-like projectile, launched from the collapsing North tower, that hits Building 7.
