Photo courtesy of the Port Authority

When the final part of the spire was lifted and installed on to the top of One World Trade Center, the Port Authority attached a camera to the bottom—remember this video, delivering 9 full minutes of vertigo that's still making our palms sweat? Anyway, around that time they ALSO took some other photos... FROM ABOVE, like this one.

We recommend you view it in full size to get the real nauseating, sweating, vertigo experience. They Tweeted the pic out yesterday, noting the brave men in this photo are ironworkers installing the final sections earlier this month—"Working above 1,700 feet in the air!"
