WTC 7: Fires Fuelled by Office Furnishings. Be AFRAID

uh... yeah... I guess it would make sense that a fire would burn shit that is combustable... like furnature?

1. Is this why they make the smokers go outside? They don't want them accidentally lighting up the office furnishings because the whole building would come down? LOL
No... they make smokers go outside because leftists forced them to. Now- you can't even smoke outside. It's for the children...

Make the measurements yourself!
In discussing my measurement of the freefall of Building 7 with one (reluctant) physics professor, the professor at one point protested, “I’ll take your word for it, for the sake of argument, but I have no way to confirm your claims for myself.â€
That comment astounded me because I see the motion of the building as such a straightforward measurement. But upon reflection I recalled all the time and energy and collaboration that went into gathering all the necessary materials and information for the measurement: a suitable video, an appropriate software tool to make measurements on the video, calibration data, knowledge of video formats, etc. I realized that even with the requisite knowledge base and skill set, it would take a very motivated person to reproduce my measurements. I therefore collected together all the bits and pieces that went into my measurement and present them here as a kit that can be used by a physics teacher or handed to a motivated physics student as a lab assignment or project or science fair entry. The skills that will be learned in the process will serve a physics student well for other projects that might involve using video as a measuring tool.
All the tools and material needed are free and downloadable here:

Maybe I am thick but if I remember my physics correctly ... I'm far from being a physics expert and figured this would be a good place to ask a beginner question that has been confusing me for some time.
According to Galileo, two bodies of different masses, dropped from the same height, will touch the floor at the same time in the absence of air resistance.
BUT Newton's second law states that a=F/m , with a the acceleration of a particle, m its mass and F the sum of forces applied to it.
I understand that acceleration represents a variation of velocity and velocity represents a variation of position. I don't comprehend why the mass, which is seemingly affecting the acceleration, does not affect the "time of impact".
{Frank's Answer} it is because the Force at work here (gravity) is also dependent on the mass
gravity acts on a body with mass m with
F=mg
you will plug this in to
F=ma
and you get
ma=mg a=g
and this is true for all bodies no matter what the mass is. Since they are accelerated the same and start with the same initial conditions (at rest and dropped from a height h) they will hit the floor at the same time.
This is a peculiar aspect of gravity and underlying this is the equality of inertial mass and gravitational mass (here only the ratio must be the same for this to be true but Einstein later showed that they're really the same, i.e. the ratio is 1)
-----------------------------------------------------------------------------------------------------------------------------
ACCEPT... When other shit gets in the way. i.e. An object in motion remains in motion unless acted upon by an outside force- in this case 1 being gravity and 2 being obsticles in it's path of travel.
That shit being the rest of the building.
Now- in the linked video in the OP that wild bill would have you go to doesn't really explain anything other than to offer up a quick repeat of 8th grade physics.
So what is wild bill trying to say?
David Chandler is saying... **** all... I could never really figure that out. David basically says WC7 fell at a rate different than that the official report says and therefore it's proof that Bush is an evil Lizard being who caused 9/11 himself.
I might have condensed the theory down a bit- but I think that's what he is on...other than LSD...
