A United Airlines flight from Houston to San Francisco landed safely in Albuquerque, N.M., Tuesday morning after the co-pilot became ill.

An airline spokesman says the co-pilot of United's Flight 1614 lost consciousness and  the plane was diverted to Albuquerque, New Mexico.

The plane landed at 8:20 a.m., he added, with the co-pilot unconscious but in stable condition.

An airline statement said: "The crew followed procedures and the aircraft landed safely. We are working to get our customers to their final destinations"

The pilot was reported to have regained consciousness and walked off the plane in Albuquerque under his own power.

It was not immediately clear what caused the pilot to lose consciousness.

The incident follows the death of Michael Johnston-an American Airlines pilot- who on Monday, suffered a heart attack and died during a flight from Phoenix to Boston.
