A small plane carrying five people slid off the runway after landing at a Monmouth airport.

The accident occurred shortly before midnight Tuesday at Monmouth Executive Airport in Wall. The Learjet 55 landed without incident, but then continued off the end of the runway and down an embankment before coming to a stop in a grassy area.

Two pilots and three passengers were able to safely exit the aircraft a short time later. No one was hurt.

The airport manager tells News 12 New Jersey in the pilot's 35 years of flying, this is the first major incident he's faced during his career.

It's not yet known what caused the accident, which will be investigated by the Federal Aviation Administration and the National Transportation Safety Board.
