Investigation Summary
The accident occurred while the RF-4B, assigned to Marine Tactical Reconnaissance Squadron 3 (VMFP-3), was en route to the aircraft carrier USS Midway. Shortly after departing Atsugi, the crew experienced a technical malfunction involving a fuel leak in the engine compartment, which resulted in an uncontrollable engine fire. Both the pilot and the reconnaissance officer successfully ejected from the aircraft and landed safely. The Phantom II, however, continued its descent into the Midori-ku district of Yokohama, striking the home of the Doshida family. The impact and subsequent fuel-fed fire destroyed several buildings. Two brothers, aged 1 and 3, died that night. Their mother, Kazue Doshida, survived the initial crash with severe burns but underwent dozens of skin grafts and surgeries before passing away in 1982. The accident caused significant diplomatic tension between the United States and Japan regarding the safety of U.S. military operations in densely populated Japanese areas.
Final Conclusions
The crash was attributed to a mechanical failure that caused an in-flight fire, rendering the aircraft unflyable. While the flight crew survived by ejecting, the resulting ground impact caused three civilian fatalities. The tragedy is commemorated by a statue in Yokohama and was the subject of the 1984 anime film 'Mamma, Poppa Bye Bye'.
