From the very top of One World Trade Center, One World Observatory can see just about everything in New York City. While up on the 102nd floor, you can rent an iPad which has a special app on it containing augmented reality bits of information over the skyline you are seeing, plus these short, informative videos telling you what you are looking at. The One World Explorer app videos are now online, and in this one, learn about the Chrysler Building and the battle for World's Tallest Skyscraper.
