==Test bombs: mall, theater, 747 airliner==
{{Main|Philippine Airlines Flight 434}}
Yousef's first operational test of his bomb was inside a mall in [[Cebu City]]. The bomb detonated several hours after he put it in a generator room. It caused minor damage, but it proved to Yousef that his bomb was workable.{{Citation needed|date=January 2010}} On December 1, 1994, Yousef placed a bomb under a seat in the Greenbelt Theatre in Manila to test what would happen if a bomb exploded under an [[airline seat]]. The bomb went off, injuring several patrons.

Following this incident, Yousef booked the Manila-Cebu leg of the [[Narita International Airport|Narita]]-bound [[Philippine Airlines Flight 434]] under the alias Armaldo Forlani, using a forged Italian passport. During this leg, he built another bomb, which had one-tenth of the power that his final bombs were planned to have, in the lavatory of the aircraft, setting the timer for four hours. Yousef planted the bomb inside the life jacket pouch of seat 26K, which he moved into after takeoff, and disembarked in [[Cebu City|Cebu]]. 

The bomb exploded while the aircraft was over Japan's [[Minamidaitō]] Island, part of [[Okinawa Prefecture]], killing Haruki Ikegami, a Japanese businessman occupying the seat; an additional 10 passengers were injured. The flight was carrying 273 passengers in total. The blast blew a hole in the floor, and the cabin's rapid expansion severed several control cables in the ceiling, cutting off control of the plane's right aileron, as well as both the captain's and first officer's steering controls. Usually, 26K, the seat that Yousef chose to plant the bomb, would be positioned directly over the centre fuel tank, and the detonation of the bomb would have caused a crippling explosion, but on this particular airframe, a former [[Scandinavian Airlines]] aircraft, the seat was two rows forward from normal. The flight crew kept control of the [[Boeing 747-200]] and brought it into an emergency landing at Okinawa's [[Naha Airport]]. Satisfied with the deadly results of the attack, Yousef then planned which flights to attack for "Phase II" of the plot.
