Because of the self imposed cone of silence, nobody has confirmed the evac took place. What has been confirmed, and just shoot me if this is not allowed to be said, but several passers by confirmed to LT and he stated it, that there was activity around the plane.

You all know what that means. And an Evac is a demonstration, ongoing until the FAA says it is over. It is not pass/fail. It is, show the FAA that you can perform the evac and ditching to their satisfaction and also perform it as described in your manuals.
