An American Airlines plane carrying 60 passengers and four crew members collided with an Army Black Hawk helicopter outside Reagan National Airport near Washington, D.C. Wednesday night. A D.C. fire official said Thursday that “we don't think there are any survivors from this accident" and "we are switching from a rescue operation to a recovery operation.

The Federal Aviation Administration says an American Airlines plane arriving at Ronald Reagan Washington National Airport discontinued its landing, performing a go-around to avoid getting too close to another aircraft departing from the same runway.

In recent weeks, North America has seen four major plane accidents. These include a commuter plane crash in Alaska on February 6, which claimed all 10 lives on board, and a mid-air collision on January 26 between an Army helicopter and an American Airlines flight at National Airport,
