J. M. Berger recently wrote a piece about the origin of the word Bojinka. Bojinka was the name of a plot in which WTC bomber Ramzi Yousef, alleged 9/11 mastermind Khalid Shaikh Mohammed and others intended to attack Boeing airliners, most famously by blowing 11 or 12 up on their way to the US. There has been some speculation about the word’s origin, as it is thought to be Serbo-Croatian (KSM fought in Bosnia), but it is usually claimed that the word bojinka does not exist in that language.
