FAA Grounds El Paso Airspace for 7 Hours After Border Agents Fire Military Drone Laser

U.S. airspace over El Paso shut down for seven hours this week after border agents used a military anti‑drone laser near the city’s international airport, in what local officials called an unprecedented security move that disrupted commercial and medical flights for thousands of travelers.nytimes +1 The Federal Aviation Administration (FAA) had initially announced a 10‑day grounding through Feb. 20 for “special security reasons” before abruptly reversing course early Wednesday.apnews

The episode began late Tuesday, when the FAA classified the skies over El Paso and parts of southern New Mexico as national defense airspace up to 18,000 feet, halting all flights at 11:30 p.m. MST and warning that aircraft violating the order could be intercepted and that the U.S. government “may use deadly force” against any aircraft posing an imminent threat.apnews +1 Administration officials publicly tied the move to a “cartel drone incursion,” even as subsequent accounts from multiple agencies pointed to confusion over the use of a high‑energy laser system and reports that the suspected drone was, in fact, a metallic party balloon.nytimes +2

How a Border Laser Test Escalated Into an Airspace Lockdown

According to multiple U.S. officials and media reports, the Pentagon had recently deployed the Army’s LOCUST high‑energy laser system — a roughly 20‑kilowatt directed‑energy weapon built by AeroVironment — near Fort Bliss, adjacent to El Paso International Airport, to counter small drones used by Mexican cartels.reuters Customs and Border Protection (CBP) personnel trained on the system fired at what they believed was a cartel-operated drone crossing the border, an object later described by people briefed on the incident as a mylar party balloon.nytimes +1

The FAA responded by imposing the sweeping temporary flight restriction while it assessed the safety implications of operating a powerful laser so close to commercial flight paths.forbes +1 Transportation Secretary Sean Duffy later said on social media that “the threat has been neutralized, and there is no danger to commercial travel in the region,” framing the incident as a successful response to cartel drones.npr But officials at the Defense Department and FAA privately clashed over whether the laser use and any planned follow‑on testing had been properly coordinated before civilian airspace was closed.forbes +1

Fallout in El Paso: Canceled Flights, Medevac Diversions and Demands for Answers

The shutdown, which ultimately lasted about seven hours instead of the announced 10 days, led to at least 14 flight cancellations, diversions of additional flights and the rerouting of medical evacuation aircraft, including to nearby Las Cruces, New Mexico.apnews +1 El Paso International, which handled roughly 3.5 million passengers in the first 11 months of 2025, warned of significant potential economic impacts had the closure continued; one city representative estimated losses could have reached $40–50 million over 10 days.cbs19 +1

Local leaders said they were blindsided. Mayor Renard Johnson said the move caused “chaos and confusion” and that “you cannot restrict airspace over a major city without coordinating with the city, the airport, the hospitals, the community leadership.”thedebrief Democratic Rep. Veronica Escobar, who represents El Paso, questioned the administration’s explanation, saying the information she was receiving “does not add up” and demanding a full accounting of which agencies ordered the shutdown and why.npr +1 Airline crews, caught off guard by the sudden ground stop and the aggressive enforcement language in FAA advisories, expressed confusion in recorded air‑traffic control audio.cbs19

The Bigger Picture

The El Paso incident exposed how the rapid deployment of military‑grade counter‑drone technology on the U.S.–Mexico border — where the Pentagon has reported more than 1,000 drone sightings a month — is colliding with the realities of crowded civilian airspace.reuters As investigations and congressional oversight ramp up, the central questions now are whether agencies followed existing protocols, whether those protocols are adequate for directed‑energy weapons near major airports, and how to balance an evolving cartel drone threat against the risks of misidentification and sudden airspace shutdowns over a major American city.
