Hope there is some people to double check SS's work. Remember that clown on the hang glider? Houston would be very symbolic, everyone should remain on their toes. It goes to show that at those times people weren't thinking in dimensions. Threats can come from above and below, remember Kennedy? I would be advisable also to have someone or thing, walk the path first. I was the only one on 911 that had lodged girders removed from adjacent buildings; 3D.
