ABERDEEN, S.D. (NewsDakota.com) – The Civil Air Patrol (CAP) continued searching on Sunday for an aircraft that went missing last week, presumably between Aberdeen, South Dakota, and Oakes, North Dakota over the weekend. Nearly 90 personnel and four aircraft from units in both states participated in Sunday’s efforts.

According to a release, the missing aircraft is a single-engine Cessna 172, white with light blue markings. It had one person on board. Authorities believe the missing aircraft has an emergency locator beacon but no signal has been detected.

The CAP is asking pilots flying in the area to be on the lookout for more aircraft than usual. CAP aircraft are red, white, and blue in color.

CAP is working closely with officials from Brown County Sheriff’s Office and Emergency Management. Anybody with information about this incident should contact the Brown County Dispatch Office at 605-626-7911.

The air and ground search will resume on Monday.
