Overview edit

The aircraft involved in the incident was a Douglas DC 8-63F with the registration number N785FT and serial number 46009, and powered by four Pratt & Whitney JT3D-7 engines. The aircraft was delivered to Flying Tiger Line on November 19, 1968. At the time of the incident, the aircraft had accumulated a total of 6047.2 hours.[2] The aircraft took off from Los Angeles International Airport at 20:53PM on July 25 and after 3 scheduled stops arrived at Haneda Airport at 22:44PM on July 26. The aircraft and crew stayed over at Tokyo for the night before taking off on 9:29AM for Naha Air Base.[1][3]

The aircraft was making its final approach to Naha Air Base's Runway 18 using precision radar approach at around 11:35AM when the aircraft's rate of descent increased and subsequently crashed 2,000 feet short of the runway.[1][3][4] All four crew members did not survive the crash.[1]

Cause edit

Flying Tiger Line Flight 45 flew from Tokyo to Naha using IFR, and crashed on final approach just as it had passed a low level raincloud.[1][3]

The investigation by the National Transportation Safety Board concludes that the aircraft encountered a tropical storm while on approach with visibility not reaching 1 mile, only for visibility to increase by 10 to a 100 times once the clouds cleared, blinding the piloting crews and making the approach difficult.[4]
