why didn't it flow away at 1200F versus 1700F? Well you are making the false assumption that the metal was pure. If it was an aluminum alloy, or aluminum with impurities (organic, other metals, etc...) then the color for a given temperature would be different, hence making the scale inaccurate.
Yes, but you are also ignoring the post regarding burnt aircraft. In those cases the fuselage burned up and didn't melt. What makes you believe the aircraft in the WTC were different? Impurities like organic material would come from what? and would dilute into the metal? Not really, they'd just float to the top and burn.
BTW are you trying to imply that impurities would raise the melting point from 600º to 1200º?
