The Public Health Service in Costa Rica owned and operated a white helicopter with red lettering on the side. It is unknown what make or model it was. It was sent by the Costa Rican Government as part of the cover up to destroy any aberrant forms or evidence of dinosaurs. The helicopter transported several uniformed men armed with flamethrowers to the beach where the aberrant form was found. The uniformed men carried by the helicopter burned the carcass until there was nothing left, and the evidence disposed of, returned whence they came.
