A Douglas C-54D aircraft crashed on Taboga Island, killing all 23 on board. The aircraft operated a flight from West Palm Beach, Florida, to Panama City. The pilot filed an IFR flight plan but lacked an instrument rating. Weather at Taboga Island was reported as a ceiling of approximately 750 feet above sea-level with visibility of 15 miles, with a cloud cover of 250 feet and 1/16 mile visibility. While descending towards the destination airport, the airplane struck a mountain slope on Taboga Island. The investigators believe the pilot sighted Otoque Island and mistook it for Taboga, and that he was in the vicinity of Otoque Island when he gave his estimated position of 15 miles southeast of the field. He thought he was past Taboga Island, approaching Albrook Field, and by dropping down a little, he would be contact again. The estimated distance of 10 miles traveled would place him over Taboga from Otoque.A Douglas C-54D aircraft crashed on Taboga Island, killing all 23 on board.
