A medical transport jet with six people on board plummeted to the ground near the Roosevelt Mall in Northeast Philadelphia Friday night, bursting into flames that spread to homes and cars in a heavily trafficked area and killing everyone on board the plane and at least one person on the ground.

A medevac plane crashed soon after takeoff in Philadelphia on Friday with a child and five others on board, the air ambulance company that operated it said, adding that it had not confirmed any survivors.

As of Saturday morning, officials said there were seven dead — six on the jet, one person on the ground — and 19 injured. The plane hit the ground just after 6 p.m., during a busy Friday evening dinner hour. Philadelphia Mayor Cherelle Parker said the plane was aloft for a very short period of time before it crashed.
