MIA Hunters was a Minnesota-based volunteer nonprofit organization dedicated to finding and recovering the remains of lost American pilots air crew members missing in action from World War II. MIA Hunters organized at least 34 missions to China, Papua New Guinea, Vietnam, the Philippines, and elsewhere to locate the remains at crash sites and unmarked graves, without any charge to the families. They located a number of aircraft associated with milestones in military history, among them the Doolittle Raid and Operation Tidal Wave.
