I looked it up here is the link
It says its 4 miles. If Trump had good field glasses he could see it.
And the map, which I couldn’t copy indicates that distance along streets with a dog leg, not straight line of sight. And it was a perfect clear, cloudless, crisp day with outstanding visibility. For years I had a direct view to the south from the 47th floor at 42st and Lex. On a day such as the fatal one, the ribs of the WTC stood out clearly in my 300mm zoom lens. With the morning sun hitting the east faces the contrast of falling bodies against the clear blue sky would have been stark. Somewhere I have spectacular photos of the view soutj to the WTC with the Jersey shore visible beyond.
Suggest folks view the map on your link to see the crooked street path of travel.
