This weekend's training exercises for the Oregon Civil Air Patrol (CAP) turned in to the real thing when the Air Force Rescue Coordination Center requested their assistance in a real search for a missing plane. The CAP spent most of Sunday searching for a Bellanca single-engine aircraft with three people on board that left the Dalles Saturday afternoon headed for Wyoming, and never reached the destination. The CAP launched five planes early Sunday morning to join the search, and one of the crews spotted what may be wreckage in a mountainous area of Umatilla County. A ground team from the Umatilla County Sheriff's Office was working its way into the remote area late Sunday afternoon. No information about the people on the plane has been released.
