to see this effect on a smaller scale, take a piece of metal, like a coat hanger and bend it back and forth in the same point until it breaks, then feel the tips, they will be very hot, when metal gets stressed, it heats up. Further, the debris would insolate the heat in the ground

There are plenty of exotic metals in an office building to start a nasty fire like we see falling from the window. Magnesium has a low ignition point, and burns extremely hot, hot enough to light aluminum and several other exotic metals. My computer case is magnesium aluminum alloy, when I was modding one of the face plates with a dremmel, it lit up, luckily I had a bucket of sand near and I was able to smother it. I think it could have come from a large UPS, large batteries contain loads of exotic metals. Lithium Ion batteries will ignite and explode when heated past 180C (lithium’s melting point) in a gorgeous display. Alkaline batteries contain magnesium, point is, and there are plenty of things that could cause that drip, besides thermite, which can’t be used to sever vertical beams anyways.
