Exploding pagers and radios don't move the needle with regard to airport security.

Presently screening is conducted on multiple levels, from tactile to x-ray to topographic scans to other means of detecting threats. Whether it's a pager or laptop, it still undergoes the same screening.

On numerous occasions, I've personally carried plastic explosive and other contraband through airport security, and have been caught. Every time was a training event in which I was assigned to carry items through checkpoints and other places, to check, train, and test personnel, equipment, and animals. Whether it's plastic explosive taped to my abdomen, inside my suitcase, or in equipment, or other equipment, the means to detect are considerable, varied, and effective. That pagers in use by a terrorist organization in an unstable region were used against the terrorists doesn't change the nature of screening in the US; anyone bringing those pagers through would have been subject to the same screening before, or after, in the US. Further, because of this screening, it doesn't change our position or exposure in the cockpit, or on the secure side of the security checkpoint.
