All on board passenger jet feared dead after collision with Army helicopter near DC

An American Airlines jet with 60 passengers and four crew members aboard collided Wednesday with an Army helicopter while landing at Ronald Reagan National Airport near Washington, D.C., prompting a large search-and-rescue operation in the nearby Potomac River.

At least 28 bodies were pulled from the icy waters of the Potomac, officials said.

Crews were still searching for other casualties but did not believe there were any survivors, which would make it the deadliest U.S. air crash in nearly 24 years.

The body of the plane was found upside down in three sections in waist-deep water. The wreckage of the helicopter was also found. Three soldiers were on board.

Investigators from the Federal Aviation Administration will join the National Transportation Safety Board (NTSB)-led investigation of the midair collision
