A more sophisticated form of underwear bomb has been developed, but the CIA has thwarted an attempt to deploy it to blow up a US based plane.
The plot involved an upgrade of the underwear bomb that failed to detonate aboard a jetliner over Detroit on Dec. 25, 2009. [it has] a more refined detonation system…
… the device did not contain metal, meaning it probably could have passed through an airport metal detector.
But it was not clear whether new body scanners used in many airports would have detected it.
The bomber, who was with an al_Qaida affiliate based in Yemen, had not yet picked a target when the FBI wen in and grabbed the underwear. It is not clear if the would-be bomber was wearing, or otherwise near, the underwear at the time it was seized, but that would have been a hella wedgie.
NPR and other outlets are reporting this.
The current disposition of the bomber him or her self is not being reported at the moment.
