Ramzi Yousef attempts a trial run of Operation Bojinka, planting a small bomb on a Philippine Airlines flight to Tokyo and disembarking on a stopover before the bomb is detonated. The bomb explodes, killing one man and injuring several others. It would have successfully caused the plane to crash if not for the heroic efforts of the pilot. [Los Angeles Times, 9/1/2002; US Congress, 9/18/2002] A man telephones the Associated Press and claims the attack was the work of the Abu Sayyaf, a Philippine militant group. One Bojinka plotter will later confess that the caller was Yousef. Yousef makes the call as part of a long term cooperation arrangement with the Abu Sayyaf. [Los Angeles Times, 5/28/1995] Yousef has been working with the Abu Sayyaf for several years and members of the group are deeply involved in the Bojinka plot (see December 1991-May 1992 and Late 1994-January 1995).
