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.

On Saturday, officials are bringing salvage equipment to help remove the passenger plane and helicopter and retrieve the rest of the bodies.

An air ambulance carrying six people crashed near a mall in northeast Philadelphia on Friday evening, the company that operates the aircraft said.

The plane had been on a medical transportation mission to Mexico, carrying a child patient, her mother and four crew members.

All 6 people on board the plane are dead and one person on the ground was killed in Friday's crash, Mayor Parker said Saturday. At least 19 others were injured.
