That is Edna Cintron standing at the opening of a plane shape hole that was left in the South Tower of the WTC on 9/11. She was captured on many pictures and videos, in which she is waving(for help) in some of them. This gave her the nick-name “The Waving Woman.”
There is a whole conspiracy that revolves around this. Some people say that this is proof that there was no jet fuel. Some people think her pants are “too white” for someone who just walked through all that debris. There is a picture of her CNN memorial picture that shows it was edited 6 months prior to the crash. Endless amounts of conspiracies. Whatever you choose to believe, I think this picture is one of those unique ones that really needs an explanation. Maybe one of you guys can give it one.
