> Our voices echoed away into a bottomless pit [of the elevator shaft]

Would voices actually "echo away" in a literally bottomless pit?

Yes. Even standing outside a straight-through tunnel, you can get some echo back to you off the walls.

The bottom of the bottomless pit is just a regular pit?

		If true, then it would still take a looooong time for the first echo from it. But the walls will echo almost instantly.
