San Diego International Airport ground to a halt Friday afternoon in one of the more bizarre aviation disruptions the region has seen, and by Saturday, with residual delays still working through the schedule, two separate mysteries remained only partially resolved: who was flying a drone near the control tower, and what exactly was the giant silvery object residents across the county spotted drifting far above the city at the same time.
According to San Diego International Airport, personnel identified two objects in the immediate vicinity of the airfield at approximately 2 p.m. Friday: a drone and a weather balloon. In response, the Federal Aviation Administration temporarily paused all arrivals and departures. Witnesses described the drone as hovering roughly 20 to 25 feet above the air traffic control tower itself, among the most serious violations of FAA airspace rules given how directly it endangered both the facility and the aircraft it was guiding. The ground stop lasted approximately two and a half hours, with an all-clear issued around 4:30 p.m., but the disruption cascaded through the evening. Hundreds of flights were delayed, arriving aircraft were held in patterns over the Pacific, some flights diverted to alternate airports, and by 8 p.m. San Diego was being described as one of the most delayed airports in the country during the peak of the disruption.
The airport confirmed that Airfield Operations is coordinating with the FAA, the Transportation Security Administration and local law enforcement, and that TSA law enforcement is actively investigating the drone activity. As of Saturday, no operator has been publicly identified. Early reporting indicated police were initially unable to locate the person responsible, and it remains unknown whether the drone was transmitting Remote ID tracking data, the FAA-mandated broadcast signal that functions as a kind of license plate for drones and is often the fastest way investigators trace an unauthorized flight back to its owner. Flying a drone within five miles of a controlled airport without authorization is a federal offense; hovering one at tower height compounds the violation substantially. Penalties under federal law can reach $20,000 per violation, with criminal prosecution possible where investigators establish reckless endangerment.
The second object is where the story gets stranger, and where the available evidence points toward a far more mundane explanation than the drone. As the ground-level incident was unfolding, residents across San Diego separately reported a silvery, reflective object visible high in the sky, prompting speculation ranging from a military craft to an unidentified aerial phenomenon. Flight-tracking data identified the object as HBAL124, registration N519HB, a high-altitude balloon recorded near 53,800 feet and moving at roughly 53 knots over inland San Diego County, an altitude and description consistent with a stratospheric platform rather than anything connected to the airport disruption itself.
That registration traces to Sceye Inc., a New Mexico-based company developing high-altitude platform stations, unmanned, solar-powered airships designed to loiter in the stratosphere for weeks, providing communications and remote-sensing coverage over rural and underserved areas. Sceye has flown this same aircraft on test missions dating back to 2024, launched from Roswell Industrial Air Center, and has previously confirmed such flights when contacted directly by reporters. The company had confirmed days earlier that this particular ST1 platform remained airborne on a return journey across the Pacific from a mission over Japan, and the altitude and trajectory tracked over San Diego are consistent with that return leg. Sceye has not yet issued a formal statement confirming HBAL124 is that same aircraft, though the circumstantial case is strong.
Crucially, airport officials have been specific in describing the drone and weather balloon that triggered the ground stop as being in the immediate vicinity of the airfield, language that does not match the high-altitude craft spotted region-wide at nearly 54,000 feet. There is no public evidence tying the Sceye airship to the airport shutdown at all. The two events appear to be an odd coincidence of timing rather than a single incident, even though photos and social posts circulating over the weekend blurred that distinction for many residents trying to make sense of an unusually strange Friday sky.
What remains genuinely unresolved is the incident that actually mattered operationally: the drone that shut down arrivals and departures at a busy West Coast airport during a holiday travel weekend. Unlike the Sceye airship, whose owner and purpose are public record, the drone’s operator has not been identified, and the TSA investigation remains open. That gap matters. Drone incursions at major airports have become a recurring national concern, and cases like December’s LaGuardia scare or last fall’s Amsterdam and Munich shutdowns were later traced to routine air traffic, celestial objects, or unconfirmed sightings rather than confirmed hostile activity. San Diego’s case differs in one respect: airport officials have affirmatively confirmed a drone was present, not merely that pilots or residents reported seeing one.
For travelers, the practical guidance from the airport and the Department of Transportation is straightforward: passengers affected by delays tied to the ground stop retain standard refund and rebooking rights, and residual delays are expected to continue clearing through the weekend as the network recovers. For the broader question of who flew a drone directly above San Diego’s control tower, and why, the honest answer as of Saturday is that nobody outside the investigation knows, and the TSA has given no timeline for when, or whether, that will change.
