What happened
A four-engine aircraft departed San Francisco Airport at 23:05 local time, operating under Visual Flight Rules (VFR) for a short distance of approximately 10 miles toward Oakland. While performing the approach to runway 27R at Oakland, the pilot-in-command initiated a descent that went below the minimum safe altitude of 500 feet. During this maneuver, the aircraft struck the surface of the Oakland Bay, resulting in an explosion and subsequent sinking of the vessel.
The accident resulted in eight fatalities and two survivors, consisting of one passenger and one flight attendant who were rescued from the scene.
