Photos: Washington Dulles International Airport Turns 50

So much has happened to Washington Dulles International Airport since President John F. Kennedy dedicated it in 1962.

The airport, which is located on 12,000 acres in Chantilly, recently experienced a multi-million dollar expansion, which will bring a new Metrorail system, a fourth runway, expanded gates and buildings and a new airport traffic control tower. About 23 million travelers visit Dulles Airport annually, and the eventual addition of a metro line will introduce it to millions of potential flyers. 

The main terminal is unmistakable (architect Eero Saarinen called it the best building he'd ever designed) and as such has appeared in movies like "Airport," "Die Hard II" and "Body of Lies."
