A small medical jet carrying six people crashed in a Northeast Philadelphia neighborhood Friday evening, officials said, causing an explosion and setting several homes ablaze. It's unclear if anyone aboard survived.

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.
