Reply #94: " people in the lobbies saw flames shoot out of the elevator shafts "

So fuel got in the elevator shaft. You've never seen a carburetor backfire? It doesn't make your engine fall down.

In fact, the presence of the elevator shafts is a major argument against the proposition of major core fires. The fuel fall down the shafts.
It didn't ignite seriously. The firemen walked up the stairwells just
fine.
