After an Army helicopter and American Airlines plane crashed into the Potomac River around Washington, D.C., a Virginia diver shared challenges of such a recovery effort.

Recovery crews and divers are searching the Potomac River for remains and clearing wreckage from the midair collision of a passenger jet and Army helicopter that killed 67 people. A Coast Guard cutter outfitted with a crane waited by the wreckage on Saturday as occasional recovery team members slipped into the water from smaller emergency boats.
