First responders battle frigid conditions in the Potomac

American Airlines Flight 5342 and a military helicopter collided mid-air late Wednesday night near Ronald Reagan Washington National Airport. Officials believe all 64 people aboard the airplane -- 60 passengers, 4 crew members -- and the three people aboard the helicopter are dead. Officials conducted a frantic rescue effort overnight, which transitioned to a recovery effort early Thursday. Many aboard the plane were in Wichita, Kansas for a figure skating competition. A major obstacle for the first responders at the scene of the Washington, D.C., plane crash is the chilly temperatures in the Potomac River.
