SAN DIEGO -- Federal officials will unveil unmanned drone aircraft Monday that will soon be circling the skies of Southern California, using radar to find illegal border crossers.
The planes, called Maritime MQ-9 Predator B Guardian Unmanned Aircraft Systems, have already been used along the Mexican border in Arizona and Texas, and along the Canadian border in North Dakota.
