All of the "major" pieces of wreckage from the collision between a Black Hawk helicopter and American Airlines Flight 5342 have been cleared from the Potomac River, officials said.

The U.S. National Transportation Safety Board (NTSB) and Federal Aviation Administration retrieved on Friday (February 7) parts of the wreckage of a Black Hawk helicopter which collided with an American Airlines jet last week near Washington's Reagan Airport, killing 67.
