The sudden shutdown of airspace in Texas earlier this week was due to a lack of communication over the use of an anti-drone laser by Customs and Border Protection during an apparent attempt to stop operations by Mexican drug cartels, according to reports.
The use of the laser, sanctioned by the Pentagon but not relayed to aviation authorities, resulted in the sudden closure of the airspace over El Paso, Texas, by the Federal Aviation Administration late Tuesday, according to The New York Times.
