As if stewardesses didn’t have enough to worry about already, [the FAA is warning about exploding coffee filters](http://edition.cnn.com/2013/01/09/travel/volatile-airline-coffee-filters/index.html) while in the air.

It seems the prepackaged filters “are susceptible to pressure buildup and can explode when an unsuspecting attendant lifts the coffee pot to pour a cup.” :eek:

I have to wonder if this might be the real cause of 9/11.
