According to you and your version of Newtonian physics, nothing can fall at free fall because even AIR provides resistance.
But you just admitted in the other thread that it is possible for a falling body to get close to (indistinguishable from) free fall speeds based on having enough of a load to overcome the resistance? Did you not just admit that?
Who said anything about "melting steel". Are you familiar with the terms "thermal expansion", "creep", "beams walking off supports", and "the weakening of steel due to heat"?
At what temperature does steel START to lose it's strength? Now apply the stress of a load to that same, weakened steel.
Really? Then explain how the columns beneath the east mechanical penthouse failed and the penthouse fell into the building. That happened and there was no sign of these "deformities" either. Watch the video. You can see the windows breaking on the perimeter facade as the penthouse fell into the the building. Here is a photo of STEEL railroad tracks and what happened from thermal expansion. Thermal expansion caused my the SUN beating down on them.
No, that leads to NO other questions because you have not proven that NIST explanations and calculations of how WTC7 collapsed is not possible OR what the errors in their report are. You dismiss their report with evidence that is incorrect.
