A small plane has made an emergency landing with its wheels up at Connecticut’s Bradley International Airport, but no one was injured.

Airport officials say two people were aboard the twin-engine Piper Aerostar and headed to the airport north of Hartford Thursday when the pilot reported a problem with the landing gear.

The plane was initially rerouted to Worcester Airport but was directed back to Bradley, where it landed with the landing gear up shortly after 1:30 p.m.

Officials closed the airport briefly to allow for the emergency landing. The cause of the landing gear malfunction is under investigation.
