Who takes pictures of the backs of everyone’s heads?
What are these “art students” doing with so many boxes of BB-18 electrical power distribution bus bars in the Twin Towers prior to 9/11? Why do they have climbing harnesses?
I suspect the wooden construction in the pic was used as a scaffolding to place explosives and wiring in access floors like we see in the picture. The cover story was that standing in the window was supposed to be performance art, but actually that story sounds like implausible made-up jibberish.
If you notice, the guy standing in the window isn’t even wearing a harness, so they were using the climbing gear for something other than standing in the window on thier scaffold.
