What happened
The event took place over Pearl Harbor, where the aircraft executed a maneuver described as a water loop. Following this action, the plane lost altitude and ultimately sank into the water. Despite the severity of the ditching or sinking event, the outcome for the personnel on board was relatively benign. Reports indicate that there were only minor injuries among the crew, with no fatalities recorded in the immediate aftermath of the incident.
