Drug cartels are now using homemade aircraft and drones to deliver narcotics over the U.S./Mexico border.
But border patrol is using some high flying technology to track down the drugs and the bad guys.
The Tethered Aerostat Radar System, or T.A.R.S., monitors the entire border. Six blimps, from Arizona to Texas, carry specialized radar that can detect aircraft flying too low for conventional radar to detect. That includes drones and homemade low flying planes which are equipped with drop baskets.
“Our law enforcement officers will that see that on the radar and get the drugs, get the bad guys that are waiting for the drugs,” said Rob Brown, T.A.R.S. program manager.
