The FAA lifted the restrictions hours after they were put in place. Rep. Veronica Escobar stressed there is no threat to El Paso or the surrounding areas.

An industry official, who had been briefed on the matter by the FAA in a morning call and asked not to be identified, told the Tribune that the Defense Department has been operating unmanned aircraft, or drones, against drug cartel operations from a base near El Paso’s airport without sharing information with the FAA.

The Associated Press reported that the surprise closure stemmed from the Pentagon’s plans to test a laser for use in shooting down drones used by Mexican drug cartels, according to three people familiar with the situation who were granted anonymity to share sensitive details.

That caused friction with the FAA, which wanted to ensure commercial air safety, two of the people told The Associated Press. Despite a meeting scheduled later this month to discuss the issue, the Pentagon wanted to go ahead and test the laser, prompting the FAA to shutter the airspace, the sources said. It was not clear whether the laser was ultimately deployed.
