Mayor Cherelle Parker said five people are still hospitalized following a fatal medical jet crash in Northeast Philadelphia, three of whom are in critical condition.

NTSB investigators found the Learjet 55's cockpit voice recorder Sunday. The agency said it was 8 feet down at the site of initial impact. The death toll is 7, with 22 injured.

A medical transport jet with a child patient, her mother and four others aboard crashed into a Philadelphia neighborhood shortly after takeoff Friday evening, exploding in a fireball that engulfed several homes.
