End of the Year Miracle: A Stairwell Remaining in the WTC1 Core

Just noticed this in this picture I downloaded some time back:

Note the stairwell in the core section that escaped the destruction! (upper middle of photo, be sure to click to enlarge)

It's almost as if someone standing on the stairs there could have avoided death, the stairs are essentially intact. Mind-blowing.

I'm not sure this proves demolition by itself, but I think this intact stairwell tends to support the idea of demolition more than collapse-- as a straight-down collapse of that whole tower wouldn't have left this section alone, whereas you could imagine with demolition, the core sections above this core section would have been blown away before they fell straight down to smash this remaining section.
