“A small plane is missing - last seen on radar 219 NW of Cancun at 15,000ft heading toward the Gulf of Mexico. The plane, a Cirrus S22T, left Oklahoma City; FAA tells CBS News the pilot filed a flight plan to San Antonio & has been unresponsive to air traffic control instructions.” Bit of an overshoot, OKC to SAT and then ... ? Not looking good.

HOUSTON -- U.S. Coast Guard officials are trying to locate a small airplane they say went missing Wednesday while en route to Texas.

Officials say the plane took off from Oklahoma City Wednesday and was headed to Georgetown Municipal Airport, north of Austin, but diverted at some point and headed south.

Coast Guard officials say they lost contact with the pilot after the plane flew past Freeport. The New Orleans Coast Guard sent a plane into the Gulf to try and make contact with the pilot where they observed him or her slouched over in the cockpit.

Officials believe he or she was the only person aboard the privately owned Cirrus, and the pilot was unresponsive likely due to hypoxia.

A search is now underway in the Gulf of Mexico for where the aircraft likely went down.

Reportedly the aircraft was at 15,000 feet. That's the bottom end of the hypoxia envelope. There's been a Cirrus crash due to CO poisoning. We'll probably never know. The SE turn passing Waco is interesting.
