Just after takeoff from Schiphol Airport, the flight was hijacked. One of the hijackers accidentally detonated a grenade she was carrying, killing herself and severely injuring the chief purser. The lead hijacker almost immediately announced himself to air traffic control as El Kassar, hijacking the aircraft in the name of the Palestinian Liberation movement.[3] After several Middle Eastern governments refused to permit Flight 404 to land, the plane eventually touched down in Dubai, in the United Arab Emirates. After several days on the ground, the terrorists demanded the release of Kozo Okamoto, survivor of the JRA's attack on Tel Aviv's Lod Airport.[4]
After the Israeli government refused to release Okamoto, the hijackers flew the aircraft first to Damascus, Syria, and then to Benghazi, in Libya.[5] On 23 July, 89 hours after the hijacking began, the passengers and crew were released; the hijackers then blew up the aircraft, making the incident the second hull loss of a Boeing 747, and the first hull loss of a 747-200.[5] The first hull-loss was also the result of hijackers.
Maruoka escaped, and in 1977, led the hijacking of Japan Air Lines Flight 472. He remained a fugitive until 1987 when he was arrested in Tokyo after entering Japan on a forged passport. Given a life sentence, he died in prison on 29 May 2011.[6]
