However I found another interesting thing:
There are several red spots that are no where near the impact zone.(5 seconds into the 2nd video)
Why are these spots that are NO WHERE near the impact zone heating up?
Shouldn't they be cold like the rest of the building?

Thermite requires a magnesium fuse to ignite (IE: very high temperatures). Office fire and jet fuel
cannot ignite thermite.
Exothermic welding, also known as exothermic bonding, is a welding process for joining two electrical conductors, that employs superheated copper alloy to permanently join the conductors. The process employs an exothermic reaction of a copper thermite composition to heat the copper, and requires no external source of heat or current. The chemical reaction that produces the heat is an aluminothermic reaction between aluminium powder and a mixture of copper oxides (copper(II) oxide and copper(I) oxide), with chemical formula:
3CuO + 2Al → 3Cu + Al2O3 + Heat.
This chemical reaction reaches a temperature of 1,400 °C (1,670 K).
The process is marketed under a variety of names such as Cadweld, Techweld, and Thermoweld.
