Obviously ALL the fuel was atomized and ignited on impact. But let us say the impossible DID happen, and "somehow" liquid fuel survived without being atomized OR ignited.
HOW THE ****,
1. can you get an inflammable liquid, away from the midst of a fire un-ignited.
A: YOU CAN'T.
2. If you DID, and it "ran down the elevator shafts" before igniting, any "explosion" would have been "global" throughout the shaft, resulting from vapor permeating the entire shaft. Liquids don't explode; they have to be atomized or vaporized and mixed with air. So if the fuel was running DOWN the elevator shaft ****miraculously not burning****, vapors would BEGIN at the top of the WTC shafts, and ignition of the vapors (and this has all been bloody impossible anyway) would have blown out every elevator door at every accessible floor because energy always follows the path of least resistance.
This was one of the most laughable claims made by the failed grammar school physics dupes. I invite anyone to throw a cup full of kerosene across a camp fire and into a bucket on the other side and let's see what they (a) get in the bucket, and (b) if the bucket's not burning. *********** HILARIOUS stuff.
I guess these dupes must get double their money's worth of the 4th of July, being able to light used gun powder twice.
