I am sure you saw the internal video of the Metrodome roof collapse, but did you see the "phantom" running across the opposite sideline?

Watch this first (pay attention to the opposite 20yd line starting around 3 seconds in):

Now...watch this one. Play it a few times...

Tell me that doesn't look like a horse galloping!

At first, I thought it was a shadow caused by the roof collapse, but I don't think it would move in a straight line. Maybe it was a maintenance guy in a golf cart checking out the roof and then he got out of dodge when it started to collapse.

Or...maybe it was a ghost stallion.

i think its a golfcart and the video is played in high speed (time elapsed)...e.g. Bath Ruth taking extremely small quick steps when rounding the bases.

I think so too, but that goes against the statement from the Vikings that the building was empty at the time due to the threat of safety.

I think it was a dog.

When I first saw it I thought it was a worker on a cart, but do you think there is a chance that it was that "eye in the sky" camera that follows the play from above? Maybe fox had it set up the night before and when the roof collapsed it moved down the wires.

It was Favre on a golf cart shooting at the ceiling to make holes in it so it would collapse.

I noticed that too the first time I saw it...I thought it was a golf cart racing toward the tunnel for protection but the Vikings' statements don't make that likely anymore.

I thought "worker on a cart," but you're right that everyone insists the building was empty. However, the cameras were obviously remotely operated based on the various camera angles that we see.
