New York City considered building a 990 acre airport, covering Manhattan island. Proposed in 1946, the airport would have stretched 144 blocks from 24th to 71st street, and 9th Avenue to the Hudson River, standing 200 feet tall and costing 3 billion dollars. The space below would have contained restaurants, businesses and piers for ships to anchor. While it would have allowed for quick air transport directly into the heart of Manhattan, this project would have cost a ton, displaced thousands, and been a major eye sore.
