Just to clear this up a bit. Yes, the pictures in these files were available on a contractors website. They were available for anyone to download, some where password protected zip files, some were not. I originally posted them to Orlando United, and they took them down. That night I got a message from their mods asking to explain the situation and they would go from there. Once I explained how the files were obtained, they agreed it would be okay to post them on their forum. In the mean time, another user asked if he could host the files at his blog. I said it may not be a good idea, but I didn't prohibit him from doing so, as the files are not mine either. Thats when I found out about this park secrets blog.
I do not run that website, but I can say that the files are indeed legitimate.
Back on topic though, how about the supports for the tower structure? To my knowledge there hasn't been anything done like that before. Usually you think of supports as being symmetrical for the most part, but to see the supports for this tower, it truly is one-of-a-kind.
