where did all the mass of the buildings go? how can 2 110 story skyscrapers "pancake" themselves into a pile smaller than the lobby?

To me, that photo, and the video that goes along with it, is some of the most damning evidence against the "pancake collapse" people there is.

Yes the top WTC 2, pic above, broke at least 3 laws of physics.
The only way that is possible is by a force of some kind acting on the top and bottom sections of the tower. What was that energy?
If you look carefully at the vid, you can see the undamaged building bellow the tilting top starts to collapse faster then the top is toppling, taking away the pivot point of the tilt. Thus causing the top to change it's inertia to a vertical movement instead of continuing to topple.
Residual strengths of high-strength concrete (HSC) and hybrid fiber reinforced high strength concrete (HFRHSC) after exposure to high temperatures were investigated in the paper. The results showed that normal HSC is prone to spalling after exposure to high temperatures, and its first spalling occurs when the temperature approaches 400 °C (752°F). For HSC reinforced by high melting point fibers, the first spalling occurs when the temperature reaches to approximately 800 °C (1472°F), while there is no spalling during exposing to high temperatures for HSC reinforced by polypropylene (PP) fiber with a low melting point. Mixing high melting point fiber (i.e., carbon or steel fiber) with low melting point fiber (i.e., PP fiber) HSC greatly improves the properties of HSC after exposure to high temperatures.
NIST: "None of the recovered steel samples showed evidence of exposure to temperatures above 600 degree C for as long as 15 minutes."
Nist Page 180.
NIST: Within the investigation of the recovered steel, Frank Gayle's group performed a paint defermation test which showed how paint would curl or change in a certain temperature range. So they took the samples and analized them to see what kind of temperature they were exposed to by looking at the paint. Less than 2 percent of the samples which have been pulled specifically from the fire zones, despite pre-collapse exposure to fire less than 2 percent seen temperatures of 480 degrees F* which is very low relative to the temperatures to "soften or melt" steel. "Only three of the recovered samples of exterior panels reached temperatures in excess of 250 degrees C* during the fires or after the collapse. This was based on a method devoloped by NIST to characterize maximum temperatures experienced by steel members through observations of paint cracking." NIST page 181

Weren't there 6 stories of basements and garages? Just saying that even if the debris pile was ground level, it would still be at least 6 stories tall inside the basement.

^Yep. There was no energy in the buildings construction that could cause complete pulverization of concrete, office furniture, bodies etc., and it throw up and out as the building collapses.
Also how do the debunkers explain the expulsion of the towers outer mesh structure, up to 600 ft away? That's pieces weighing in the tons. Huge pieces found embedded in other buildings. It takes massive energy to do that. Gravity does not throw things laterally any distance, let alone 600 ft. Fire does not throw things anywhere (and pls don't say 'embers do' you smart arsses lol).
Why did the steel seem to snap? Hot steel DOES NOT SNAP. It bends, it buckles, it sags, it does not snap into nice easily manageable pieces.
How many times we gotta say this before it sinks in!
People seem to really have a hollywood understanding of physics.
Edit: I missed an 'i'...
