This is New York City, on the northeastern coast of the United States, where the Hudson River empties into the Atlantic at one of the world's great natural harbours — exactly the dense island skyline the title clue pointed toward. In September 2001, Al-Qaeda terrorists hijacked four commercial airplanes: two were flown into the twin towers of the World Trade Center, destroying both; one struck the Pentagon near Washington D.C.; and a fourth crashed into a field in Pennsylvania, killing nearly 3,000 people in total.
New York City sits at the southern tip of Manhattan Island, a narrow strip of land packed between the Hudson and East Rivers — one of the most densely built urban landscapes on Earth. The northeastern seaboard here forms a chain of major port cities because glaciers carved deep natural harbours into the coastline, making it the historic entry point for Atlantic trade and immigration into North America.
