PHILADELPHIA (AP) — Philadelphia’s mayor says five people hurt on the ground from a Learjet crash remain hospitalized, three of them are in critical condition. Mayor Cherelle Parker gave an update Sunday on the crash Friday evening that killed all six aboard the Learjet and one person on the ground. The Mexico-bound air ambulance crashed shortly after takeoff Friday evening from Northeast Philadelphia Airport. Among those killed was a girl who spent months being treated at an area hospital. The crash came two days after an American Airlines jet carrying 60 passengers and four crew members collided in midair in Washington with an Army helicopter that was carrying three soldiers.
