A brush rather than a collision, but enough to trigger an investigation
In the early hours of a Thursday morning at one of the world's busiest airports, two aircraft briefly touched on the tarmac — a reminder that even the most choreographed systems of human coordination carry within them the possibility of error. A United Airlines Boeing 737, arriving from Boston with 154 souls aboard, grazed the tail of a stationary All Nippon Airways plane while taxiing to its gate at Chicago's O'Hare, prompting federal investigators to ask the quiet but consequential question: where did the system falter? No one was hurt, but the incident opens a window onto the invisible complexity that governs every safe landing.
- A United Airlines 737 wingtip brushed the tail of a parked ANA aircraft at O'Hare just before 10 a.m. Thursday — minor in force, but significant enough to trigger a federal investigation.
- With 154 passengers and seven crew aboard the United flight, the stakes of even a light ground contact are never trivial, and the FAA does not treat such moments as routine.
- The incident exposes the fragile choreography of major airport ground operations, where dozens of aircraft move simultaneously and a single miscommunication can close the gap between safety and contact.
- Investigators will scrutinize radio communications, taxiway conditions, ground control directives, and pilot awareness to determine whether human error, procedural failure, or something else allowed the two planes to come together.
- All passengers deplaned normally with no injuries reported, but the FAA's findings could ripple outward — reshaping procedures, training, or technology not just at O'Hare, but at airports across the country.
El jueves por la mañana en O'Hare, dos aviones entraron en contacto sobre el asfalto en un incidente que ahora ha atraído la atención de los reguladores federales. Un Boeing 737 operado por United Airlines, procedente de Boston con 154 pasajeros y siete tripulantes, rozó la sección de cola de un avión de All Nippon Airways mientras era guiado hacia su puerta de embarque poco antes de las 10 a.m.
El vuelo 1835 de United se encontraba en proceso de rodaje cuando su punta de ala hizo contacto con la cola del vuelo 8421 de ANA, que se encontraba estacionario en una pista de rodaje separada. El toque fue leve —un roce más que una colisión— pero suficiente para desencadenar una investigación por parte de la Administración Federal de Aviación (FAA). United Airlines confirmó el incidente en un breve comunicado, destacando que los pasajeros pudieron desembarcar con normalidad. No se reportaron heridos en ninguna de las dos aeronaves.
Las operaciones en tierra en aeropuertos como O'Hare implican una coreografía intrincada: decenas de aviones se mueven simultáneamente, guiados por personal de control en tierra a través de radio. Cuando ocurre un contacto, incluso uno menor, señala una posible falla en ese sistema. La investigación examinará las comunicaciones de radio, las condiciones de visibilidad, el trazado de las pistas de rodaje y si se siguieron los procedimientos estándar.
Mientras la FAA avanza en su investigación, el foco estará en comprender no solo qué ocurrió en esos segundos antes del impacto, sino por qué fallaron las salvaguardas diseñadas para prevenirlo. Las respuestas podrían derivar en cambios de procedimientos, capacitación o tecnología en O'Hare y, potencialmente, en otros grandes aeropuertos del país.
Thursday morning at O'Hare, two aircraft came into contact on the tarmac in an incident that has now drawn the attention of federal regulators. A Boeing 737 operated by United Airlines, inbound from Boston with 154 passengers and seven crew members, grazed the tail section of an All Nippon Airways plane as it was being guided toward its gate shortly before 10 a.m.
The United flight, numbered 1835, was in the process of taxiing to its assigned gate when its wingtip made contact with the tail of ANA flight 8421, which was stationary on a separate taxiway at the time. The touch was described as light—a brush rather than a collision—but enough to trigger an investigation by the Federal Aviation Administration.
United Airlines confirmed the incident in a brief statement, noting that the 737 had made light contact with another aircraft while proceeding to the gate. The airline emphasized that passengers were able to disembark normally once the plane reached its destination. No injuries were reported among anyone aboard either aircraft, and there was no indication of significant damage to either plane.
The FAA, which oversees all civil aviation safety in the United States, has taken the incident under investigation. The agency will examine the circumstances that led to the contact, including how the two aircraft came to be in proximity to one another on the ground and whether any lapses in communication, ground control procedures, or pilot awareness contributed to the event.
Ground operations at major airports like O'Hare involve intricate choreography. Dozens of aircraft move simultaneously across taxiways and aprons, guided by ground control personnel who direct pilots via radio. The separation of aircraft during these movements is a fundamental safety requirement. When contact occurs, even minor contact, it signals a potential breakdown in that system—whether human error, miscommunication, or procedural failure.
The investigation will likely examine radio communications between the pilots and ground control, the visibility conditions at the time, the specific taxiway layout and markings, and whether standard procedures were followed. It will also consider whether either pilot had any warning of the proximity before contact occurred.
For the 154 passengers aboard the United flight, the incident appears to have been resolved without disruption to their journey. They deplaned as scheduled, unaware perhaps of how close their aircraft had come to another plane, or perhaps very aware and relieved that the contact had been so minor. The crew of the ANA aircraft, waiting on the taxiway, would have experienced the moment more directly—the unexpected contact with another plane, the immediate assessment of damage, the coordination with ground control and their own airline operations.
As the FAA moves forward with its investigation, the focus will be on understanding not just what happened in those seconds before impact, but why the safeguards designed to prevent such contact failed to do so. The answers may lead to changes in procedures, training, or technology at O'Hare and potentially at other major airports across the country.

What does it mean that one plane was "detenido en otra calle de rodaje"—stopped on a separate taxiway? Why would that matter?
It matters because it suggests the ANA plane shouldn't have been in the path of the United flight at all. If ground control is doing its job, aircraft on different taxiways shouldn't touch. The fact that they did means something went wrong in the separation system.
Could this have been much worse?
Absolutely. If the contact had happened at speed, or if it had struck a more critical part of either aircraft, you could have had structural damage, fuel leaks, or worse. The fact that it was a wingtip grazing a tail—relatively light contact—is probably why no one was hurt.
What happens now with the investigation?
The FAA will pull radio recordings, look at radar data, interview the pilots and ground control personnel, and examine the taxiway layout. They're trying to figure out if this was a communication breakdown, a visibility issue, or a procedural failure.
Do incidents like this happen often at O'Hare?
Ground contact incidents happen at airports, but they're relatively rare at major hubs because the procedures are strict and the stakes are understood. When they do happen, it usually signals something systemic that needs fixing.
What would passengers have felt or heard?
Probably a slight jolt or scraping sound, maybe a moment of confusion. But if they were deplaning normally afterward, it couldn't have been severe. The real moment of alarm would have been for the crews—that sudden awareness that two aircraft had touched when they shouldn't have.
