If I was the leader of an Islamic fascist group...

And I realized that I could shut down the entire airline industry in the UK simply by plotting to sneak explosives on, wouldn't I start concocting all sorts of ridiculous schemes, hoping to get caught by the government? No longer would the plot have to actually work -- instead, I could create a climate of reactive fear based on the illusion of my ability to implement my threat.

Food for fascist though.
