The Civil Air Patrol in Arizona, New Mexico, Colorado and Utah are searching for a small plane that was last seen leaving the airport in Page.
Television station KNXV reports (http://bit.ly/1wjtcBf ) the plane was carrying a father and son from southern California. The two were on their way to South Carolina.
The plane -- a 1961 Mooney M20B -- left Page early Friday afternoon. The Civil Air Patrol says it departed without a flight plan.
Patrol officials in Colorado say the plane had remained low for sightseeing outside of Page but hasn't been seen since.
A ground search team in Tuba City and communication team in Page are set up to aid in the search.
