create a liquid bomb as part of the Operation Bojinka plan?

"On December 11, 1994, Yousef built another bomb, which had one tenth of the power that his final bombs were planned to have, in the lavatory of an aircraft. He left it inside the life jacket under his seat, 26K, and got off the plane when it arrived in Cebu. Yousef had boarded the flight under the assumed name of Armaldo Forlani, using a false Italian passport. The aircraft was Philippine Airlines Flight 434 on a Manila to Narita route, stopping partway at Cebu. Yousef had set the timer for four hours after he got off the aircraft. The bomb exploded while the aircraft was over Minami Daito Island, near Okinawa, Japan."
