UPDATE 11-El Paso flights resume after US anti-drone system prompts sudden shutdown

A secret military laser-based anti-drone system prompted the Trump administration to ban ‌air ​traffic for more than seven hours in and out of the Texas border city of El Paso after U.S. aviation officials raised drastic concerns about the safety of commercial air traffic. The sudden closure of the nation's 71st busiest airport by the Federal Aviation Administration stranded air travelers and disrupted medical evacuation flights overnight. The FAA initially said the ‌closure would last 10 days for "special security reasons," in what would have been an unprecedented action involving a single airport.

Government and airline officials, speaking on condition of anonymity, said the FAA closed the airspace due to concerns that an Army laser-based counter-drone system could pose risks to air traffic. The two agencies had planned to discuss the issue at a Feb. 20 meeting but the Army opted to proceed without FAA approval, sources said, which prompted the FAA to halt flights. The ‌FAA lifted its restrictions after the Army agreed to more safety tests before using the system, which is housed at Fort Bliss, next to El Paso International Airport.

The White House was surprised by the El Paso ‌airspace closure, according to two sources speaking on condition of anonymity, touching off a scramble among law enforcement agencies to figure out what happened. The FAA lifted the restrictions shortly after the situation was discussed in the office of White House chief of staff Susie Wiles, the sources said.

U.S. Transportation Secretary Sean Duffy, who oversees the FAA, said the closure had been prompted by a drone incursion by a Mexican drug cartel. However, a drone sighting near an airport would typically lead to a brief pause on traffic, not an extended closure, and the Pentagon says there ⁠are more than 1,000 ​such incidents each month along the U.S.-Mexico border. FAA Administrator ⁠Bryan Bedford met with senators on Wednesday and told them there could have been better coordination about the move but did not answer detailed questions about why the agency initially planned a 10-day halt to flights, lawmakers said.

Senate Commerce Committee chair Ted Cruz, a Texas Republican, and Senator ⁠Ben Ray Lujan, a New Mexico Democrat, both called for a classified briefing to get more answers. "The details of what exactly occurred over El Paso are unclear," Cruz said. The move had stranded numerous aircraft from Southwest Airlines, United Airlines and American Airlines at the airport, which ​handles about 4 million passengers annually.

El Paso Mayor Renard Johnson said the FAA did not reach out to the airport, the police chief or other local officials before shutting down the airspace. "I want ⁠to be very, very clear that this should have never happened," he said at a news conference.

The U.S. official in charge of airport security, Transportation Security Administration Acting Administrator Ha Nguyen McNeill, also told Congress that she had not been notified. "That's a problem," said Republican Representative Tony Gonzales of Texas, who ⁠said ​there are daily drone incursions along the U.S.-Mexico border.

AIRLINES CAUGHT OFF GUARD Airlines were also caught off-guard by the early Wednesday announcement. Southwest Airlines said the effects should be minimal for its 23 daily departures scheduled.

“FAA has not exactly acquitted itself credibly, objectively, or professionally,” said Bob Mann, an airline industry consultant. "The question should be, do we get an explanation?" Trump has repeatedly threatened to deploy U.S. military force against Mexican drug cartels, which have used drones to carry ⁠out surveillance and attacks on civilian and government infrastructure, according to U.S. and Mexican security sources.

Mexican President Claudia Sheinbaum said at her daily news conference that her administration would try to find out what exactly happened but ⁠had no information about drone traffic along the border. Tensions between ⁠the U.S. and regional leaders have ramped up since the Trump administration mounted a large-scale military buildup in the southern Caribbean, attacked Venezuela and seized its president, Nicolas Maduro, in a military operation. The FAA curbed flights throughout the Caribbean after the attack, forcing the cancellation of hundreds of flights.
