Aside from theories of deffracting light, I would think the many millions of people who came and went through those towers would have a pretty good idea about its hollowness. Let's Roll is claiming as much as 2/3rds is missing. But I live in the far West and have no access to people who may have direct knowledge. It seems reasonable to me, if you work on the 99th floor and you need a key in order to get off on that floor (and no other floor), you could work in the tower your whole life and never know it is mostly hollow. But someone like a NYC bicycle courier should have excellent knowledge of what floors were being used. Someone like that could really put the theory to rest.
