The plane, a Cessna 208B, went off the end of a runway as it was taking off from a small airport in Gloucester County, according to the F.A.A. Victims were being treated at the scene, officials said.

Officials in Dolton, Ill., called the purchase a rare opportunity. But some residents questioned whether the village, grappling with a deficit and potholes, could afford it.
