In one test, TSA inspectors hid the components of a fake bomb in carry-on luggage that also contained a bottle of water. Passengers are prohibited from carrying containers holding more than three ounces of liquids, gels or aerosols through airport checkpoints.
The screeners at Albany International confiscated the water bottle but missed the bomb.
Of course, the screeners missed weapons that weren't accompanied by deadly, deadly water, so maybe it wouldn't matter. On the other hand, the imminent paper jihad is sure to keep our airplanes safe. Unless people also learn to take newspapers out of the trash.
