Analysis

The acft crashed into a reservoir shortly after departing the Antioch arpt. There were no eye witnesses to the crash. However, an ear witness stated that he heard the acft skipping along the water like the sound of a hydro-plane. He did not hear the eng, but he was listening to his tv when he heard the skipping sounds. The acft received only minor impact damage. An exam of the acft revealed no evidence of a mechanical malfunction. A pathological exam of the plt disclosed only minor physical injuries from the impact, but the exam showed that the plt had drowned. The plt's med cert was dated 1/3/83.
