From MarketDailyNews:
Our southern border is, in part, protected by the Tethered Aerostat Radar System (TARS), which utilizes moored balloons hovering at about 15,000 feet to identify low flying aircraft and missiles that may penetrate the border and cross into U.S. airspace.
“Not only will this closure mean hundreds of people will be out of jobs, but it also means our borders will not be safe, especially along the remote U.S. Mexico Border.
These defense radars detect low flying aircraft infiltrating our borders.
Without these defense radars, low flying aircraft will go undetected.
It will be open season for any drug/gun/slave smugglers, terrorists flying in with nukes, low altitude missiles, or even a full scale low elevation invasion/attack against America."
