Donuel, you are deep in paranoid conspiricy theories here. Have you ever seen a thermite reaction? Or a normal fire with some aluminium added? I have.

A few years ago I was mucking about in the garde with a simple furnace, fueled only on wood. I was melting some aluminium down on the side of it, and spilt it there accidentially. The steel bars in there melted easily. That was a whole 18" across, and had maybe 4 pounds of aluminium and 20 of wood at most in it, not a plane load of jet fuel and aluminium, plus an office load of paper, wood and plastic.


There are plenty of ways to make a thermite rection hotter, such as replacing the Aluminium with even more reactive Magnesium, or storing it in an inert atmosphere, which would allow you to use more finely divided ingrediants without them becoing oxidised by the amosphere before use. Nobody bothers, as it would cost more, and make little practical difference. If you're using a sledgehammer to crak a nut, it doesn't matter if it a 10 or 20 pound one......
