Larry Silverstein and a coterie of elected officials sign the final column. (Joe Woolhead/Silverstein Properties)

Two weeks ago, The Observer got a tour of 4 World Trade Center and called it the nicest building at ground zero, including videographic proof. The 72-story tower topped out today in a biggish ceremony (no presidents, governors or mayors were in attendance, though plenty of other local pols) led by the building’s developer, Larry Silverstein. Here is a video of the final column rising, with a full report to come later today. (Apologies about the poor audio quality. Our camera died, so we had to use our cell phone.)
