(Cody, Wyo.) – Park County Sheriff’s Office Information Officer Lance Mathess said that as of 7 a.m., the Search & Rescue Team failed to locate a missing 1963 Mooney M20C during a ground search on Sunday.
On Saturday, May 10 at 11:30 a.m., the 911 Communications Center received a request from the Twin Falls, Idaho Police Department to check Yellowstone Regional Airport (YRA) for a 1963 Mooney M20C with tail number N6704U. The plane, piloted by 84-year-old Robert Zimmerman of Hunstville, Alabama, has not been heard from since it departed YRA on Tuesday morning. Due to the size of the aircraft, they were not required to file a formal flight plan.
The plane’s only other passenger is 86-year-old Ward Zimmerman of Seattle, Washington.
A Park County Sheriff’s SAR team was deployed into the Kitty Creek drainage of the North Fork in an attempt to locate the aircraft. Inclement weather has thus far grounded all aircraft, therefore preventing any aerial search efforts. To date there have been no confirmed sightings of the aircraft.
The SAR team will be heading back into the area this morning. Also, the Wyoming Air National Guard as well as the Wyoming Civil Air Patrol will commence an aerial search as soon as weather permits.
The ground search teams are on foot and report that the area of the search is extreme rugged back country with snow depths of three to five feet and steep mountainous terrain. There is also a risk of avalanche in the area.
