A medical transport plane, carrying a child, her mother and four other people, crashed in Philadelphia Friday night near a busy mall, killing all aboard and resulting in an untold number of injuries on the ground.

The Learjet, carrying a pediatric patient and five others, crashed on Friday, killing all on board. On the ground, one person was killed and at least 19 others were injured, officials said.

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.
