re: #72 oaktree

Do you have a cite for ALCOA blowing up a lab testing the reactivity of molten aluminum?

I was aware that aluminum flake and powder are very sensitive since my father worked in an ALCOA plant that made flake (from powder). Said flake used in part for solid rocket boosters the Space Shuttles used.

As for some sort of aluminum reaction dropping the WTC Towers I would have my doubts.

Well, it’s also silly and unneeded. Planes hit towers. Impact damages structure some. Fires cause more damage and cause supports to heat and weaken (No need to melt). Eventually, they weaken enough to fail under the stress of holding everything up and the end result is a chain reaction leading to total structural failure. Pretty simple.
