Did I miss something? I recall the bombing in '93, but that was a van in the parking garage.
Otherwise, they'd better have a dome.
I was there this last December. They have bomb barriers up all around the place. We were able to walk through buildings and elevated walkways across the street and watch the progress of the rebuilding, but we weren’t able to walk on the street.
It might well be that there won’t be a parking garage underneath the buildings. The construction hole didn’t appear to be deep enough to me, but I’m not an engineer, and don’t play one on teevee.
I still like Trump's plan: rebuild WTC 1 & 2 the same only adjacent to the original foundations with those foundations as centerpieces of the memorial.
