Freefall collapse: I no longer think that the collapse speed was 'near freefall'. A portion of the collapse was approaching those speeds, but the initial collapse was slow enough for chunks of debris to get some 20-30 stories ahead of the tower top and this is evident from any (every?) collapse video.
Controlled demolitions dont destroy every single support structure, they just take out the key supports and gravity does the rest. Once floor 90 or so collapsed with the weight of 15 stories bearing down on it there was little chance that the rest of the tower would have stood, as with each floor collapsing the floor below it gets a bigger and bigger slam of kinetic energy from above. If the tower top had twisted out a little more and transferred enough of the kinetic energy outside of the column as it fell, we *may* have seen the lower tower survive, but once those first couple of floors caved a complete collapse was the only outcome imo.
Melted steel: Prove the the molten metal is steel. I presume you mean the flowing molten metal from the WTC just before its collapse? Kerosene can definitely melt aluminium, like this air france runway fire:
And several floors of the wtc were full of aluminium as they'd just been slammed by a boeing made from the stuff.
It was WTC7's collapse that first got my mind racing on conspiracy theories, but when you're forced to rule out controlled demolition (something that takes literally months of planning, kilometres of wire rigging etc) and the first hand firefighter accounts saying they were pulled from wtc7 a few hours before it came down because of structural stability fears (including creaking, groaning, raging fires, all sorts) then a natural collapse doesn't seem so unlikely.
Also, NORAD was a big thing for me for a while. Slow to act, ever changing official timeline of events, nothing made sense. But a government department showing signs of ineptitude isnt far fetched at all, unfortunately it's pretty standard.
EDIT: can't have this discussion without including
