What happened
During a night training mission conducted in the waters off San Diego, the pilot experienced a sudden loss of control over the aircraft. The machine subsequently entered an uncontrolled dive and impacted the surface of the sea. Following the impact, the wreckage sank to the bottom. There were no survivors from this incident.
Findings
Investigators examined the circumstances surrounding the loss of control during the maneuvering phase. Their analysis suggested that the pilot may have suffered from faintness or vertigo, which could have contributed to the inability to maintain command of the aircraft. However, due to the nature of the event and the lack of definitive data, the exact cause of the accident could not be determined with certainty.
