Three of the five family members injured in a single-engine plane crash in Pennsylvania after the pilot reported an open door on the aircraft were sent to a burn center for treatment, officials said Monday.

Authorities said three of the five people injured were sent from Lancaster General Hospital to a burn center in Lehigh County.

A small plane crashed into the parking lot at a retirement community in Lancaster County, Pennsylvania, Sunday afternoon, injuring the five people aboard and damaging around a dozen vehicles, according to local authorities.
