A friend of mine worked for Texas Instruments for several years. The stories he told me were incredible. And I thought they just made ICs and calculators! Silly me.
Stuff like this (the tech side of homeland security) has always fascinated me...I saw an article on here a while back that showed the next generation of unmanned arial drones...they had a 12" (yes, inch) wingspan. That just amazes me how we can squeeze all that technology into such a small package.
