FREEPORT, Texas — The Coast Guard is searching off the Southeast Texas coast after a small plane that left from Wiley Post Airport in Oklahoma City was reported missing on a flight to Central Texas.

Authorities say the Cirrus SR-22 aircraft, capable of carrying five people, was detected on radar Wednesday flying south over the Gulf of Mexico. Air traffic controllers have been unable to get a radio response from the plane’s pilot.

The plane is registered to Edmond, Oklahoma-based Abide Aviation.
