A plane crashed into a residential neighborhood near the Roosevelt Mall Friday evening causing an explosion, setting many homes ablaze and sending debris flying.

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.

Authorities are searching for answers as to why a Learjet 55 medical plane fell out of the sky in a violent crash Friday over Northeast Philly.
