ALEXANDRIA TOWNSHIP, N.J. — State police say two people were killed when a small plane crashed at a New Jersey airport.

The crash at Sky Manor Airport in Alexandria Township occurred around 12:30 p.m. Sunday.

It wasn’t immediately clear what caused the crash. No one on the ground was injured. The victims were not identified.

Federal Aviation Administration spokeswoman Arlene Salac said the Mooney M20 plane stalled while trying to land and crashed into a field.

State police and the FAA will investigate the crash.

The New Jersey crash comes the same day as officials near Buffalo, New York, announced fatalities after two small planes collided in the air and crashed in North Collins.
