Wow, that's very compelling, and hard to refute. It's as if the public was counted on to be complete idiots and ignore facts that would be played endlessly on video without applying even the most basic science to them. The truly sad thing is that this has proved largely true. Even the more conservative version of the pancake theory (the official theory) is off by 20 seconds! And the single floor pancake (which is the pancake version more consistent with the video evidence) is off by 90 seconds! ----- Original Message ----- From: "Mark E.
