Charles Timm was 39 and working as a crop duster when he disappeared on February 7, 1980. He and colleague Clarence Hopper departed West Palm Beach Airport in a twin-engine Beechcraft they had purchased months earlier while employed by the Mueller Crop Dusting Service.

Both men, residents of South Haven, Michigan, flew over the Gulf of Mexico and never returned. The aircraft was never recovered and the two are presumed to have crashed into the ocean. The disappearance remains unresolved.

Does anyone have memories of that flight, the aircraft, or the two pilots that could help fill gaps in the timeline?
