What is unique about the Ramzi Yousef plot?

• A. Operation Bojinka 1994 - first liquid-based explosive (bomb making facility accidentally blew up).
• B. A coordinated hijacking attempt in 1990.
• C. A planted bomb in a suitcase only.
• D. Aerial drone attack.

Answer: (A)

Focus on what makes Ramzi Yousef’s Bojinka plot stand out: it was a plan to conduct a large-scale, coordinated attack on multiple airplanes using liquid-based explosives. This approach—trying to blow up several in-flight targets with liquid explosive devices—was unprecedented at the time and represented a major shift in terrorist tactics toward complex, multi-airline operations. The plan even included a test scenario that led to an accidental explosion at a bomb-making facility, which exposed the scheme to authorities.

The other scenarios don’t capture that combination of scale and method. A hijacking in 1990 describes a different tactic and era, not the unique multi-aircraft, liquid-explosive concept. A suitcase-only bomb plan lacks the global, multi-aircraft scope and the innovative use of liquid explosives that defined Bojinka. An aerial drone attack is a modern concept far outside the historical context of this plot.
