List Members,
I would like to present the bridge on Mars video, the one that leads into a tunnel; but with a new comment, and some other bridge on Mars videos of other bridges.
The first video is six minutes long. Notice that the bridge leads into the tunnel. The entire mountain is visible during the first part, and the road does not appear behind the mountain. Usually, a tunnel goes all the way through a mountain and opens up on the other side. In this case, it is not so.
This strongly suggests that the road goes downwards, for example, to an underground world on Mars.
I will send the other videos as replies.
Dean
