Here are some of the deadliest plane crashes in US history

An American Airlines jet with 60 passengers and four crew members aboard has collided with an Army helicopter while coming in for a landing at Ronald Reagan National Airport near Washington and multiple people were killed. Fatal crashes of commercial aircraft in the U.S. have become a rarity. The deadliest recent crash was in 2009 near Buffalo, New York. All 45 passengers and the four crew members were killed. The collision Wednesday occurred over the Potomac River and the aircraft fell into the water. In 1982 an Air Florida flight crashed into the Potomac and killed 78.
