‘No one survived’: All those involved in Washington plane crash dead

All 64 people aboard an American Airlines jet that collided with an Army helicopter were feared dead in what was likely to be the worst US aviation disaster in almost a quarter century, officials said Thursday.

At least 28 bodies were pulled from the icy waters of the Potomac River after the helicopter apparently flew into the path of the jet late Wednesday as it was landing at Ronald Reagan National Airport near Washington, officials said.

The plane carried 60 passengers and four crew. Three soldiers were aboard the helicopter.

“We don’t believe there are any survivors,” said John Donnelly, the fire chief in the nation’s capital. “We are now at the point where we are switching from a rescue operation to a recovery operation."
