Introduction
In early 2025, the aviation community and traveling public were surprised by an unusual headline: a coyote strike United Airlines flight forced a Phoenix‑bound aircraft to turn back shortly after takeoff from Chicago’s O’Hare International Airport. Such events, while rare, prompt serious questions about runway wildlife hazards and how airports manage airfield safety. This article examines the incident in depth, explores industry data on wildlife strikes, and highlights the evolving efforts to improve aviation safety.
Understanding the Coyote Strike United Airlines Flight Incident
What Happened During the Coyote Strike United Airlines Flight?
On January 12, 2025, United Airlines Flight 1727 — a Boeing 737 MAX 9 — was preparing for departure from Chicago O’Hare Airport on a routine flight to Phoenix Sky Harbor International Airport when something unexpected occurred. Shortly after initiating takeoff, the aircraft’s landing gear collided with a coyote that had wandered onto the runway. The pilot declared an emergency and returned safely to the airport for inspection.
There were 167 passengers and six crew members on board, and emergency responders reported no injuries. United Airlines later arranged for passengers to continue their journey on a different aircraft later that afternoon.
Why a Coyote Was on the Runway
Wildlife on or near airport runways is more common than many travelers realize. Birds and terrestrial animals like deer and coyotes are attracted to the open, grass‑covered areas around airports. In Chicago’s case, local animal control reported increased coyote sightings during mating and foraging seasons, which likely contributed to the coyote’s presence near the airfield.
Wildlife Strikes: A Broader Aviation Safety Concern
What Is a Wildlife Strike?
A wildlife strike refers to any incident where an aircraft collides with an animal during critical phases of flight, most commonly during takeoff or landing. While birds account for approximately 96% of all reported aviation wildlife strikes, mammals like coyotes also contribute to a significant portion of incidents.
According to the Federal Aviation Administration (FAA), there were over 17,000 wildlife strikes reported in 2023 alone — a figure that highlights the ongoing challenges airports face in managing wildlife hazards.
FAA Data on Terrestrial Mammal Strikes
FAA wildlife strike reports reveal that terrestrial mammals like deer and coyotes have been involved in millions of strike reports over the past decades. Notably, coyotes make up a meaningful percentage of wildlife strikes that cause notable aircraft damage.
While bird strikes often damage engines or windshields, strikes involving animals such as coyotes typically occur on the runway surface, affecting landing gear and fuselage components — as in the coyote strike United Airlines flight.
Why the Coyote Strike United Airlines Flight Returned to O’Hare
Pilot Response and Safety Protocols
After the collision, Flight 1727 quickly communicated with Chicago air traffic control, and the crew elected to return to O’Hare as a precautionary measure.
The pilot’s decision emphasized aviation industry protocols: any suspected structural damage or anomaly must be investigated before continuing flight. Although the aircraft had gained altitude, the crew’s primary concern was potential harm to the landing gear and nose structure.
Such protocols aim to maximize passenger safety even when no visible damage has occurred.
FAA Investigation and Standards
The FAA is responsible for investigating wildlife strike incidents and offers guidance on reporting and response. After the coyote strike United Airlines flight event, the FAA confirmed an investigation into the aircraft’s landing gear and the conditions leading up to the collision.
How Airports Work to Prevent Wildlife Strikes
Wildlife Management at Major Airports
Airports implement wildlife hazard management programs designed to keep animals away from operational areas. These programs vary by location but often include:
-
Habitat modifications to discourage nesting or burrowing near runways
-
Scheduled monitoring and patrols of airfield perimeters
-
Scare tactics or humane removal of animals found on or near runways
-
Collaboration with wildlife biologists to develop long‑term strategies
Such measures have been shown to reduce the number of wildlife strikes, but they cannot eliminate the risk completely.
Challenges With Terrestrial Animals
Bird deterrence is often one of the most mature areas of wildlife management. However, terrestrial animals like coyotes present distinct challenges:
-
They can travel long distances under fences or through adjacent land
-
They are active at dawn and dusk — times when flights are common
-
Their unpredictable behavior makes detection difficult
All these factors contributed to the coyote strike United Airlines flight incident.
Expert Perspectives: What Aviation Professionals Say
Pilot Safety and Wildlife Encounters
Pilots and aviation safety experts stress that wildlife encounters are unpredictable but manageable when standard protocols are followed. Training ensures that flight crews respond calmly and efficiently, as was the case during the coyote strike United Airlines flight incident.
According to aviation safety trainers, making a precautionary return to the airport — even if no major damage is apparent — is consistent with best practices when there is uncertainty about aircraft integrity.
Airport Wildlife Management Experts
Wildlife biologists working with large airports note that habitat changes around airports often temporarily displace animals, pushing creatures like coyotes into new areas including runways. As urban sprawl continues, these interactions could increase unless management strategies evolve.
What This Means for Passengers and Future Flights
Passenger Safety
The coyote strike United Airlines flight incident underscores one key fact: modern aviation safety systems work. Even in rare and unusual encounters with wildlife, passengers and crew remained safe and the aircraft returned without injuries reported.
Airline and Airport Preparedness
Airports and airlines continue to refine their processes to reduce wildlife strikes, including increased surveillance technology and improved animal deterrent systems.
A Closer Look: Wildlife Strike Numbers and Safety Trends
Long‑Term Data Insights
FAA data shows that wildlife strikes are occurring more frequently as air travel increases, but advances in detection and avoidance technology have reduced the percentage of strikes that cause serious damage.
Lessons From Other Wildlife Strike Events
The aviation industry has faced other wildlife strike events — such as bird strikes and even rare cases involving larger mammals — which have consistently shown that prepared crews and robust safety protocols save lives and equipment.
Conclusion
The coyote strike United Airlines flight incident at Chicago O’Hare serves as a powerful reminder that wildlife strikes — even those involving mammals like coyotes — remain a real, though rare, risk in aviation. Thanks to thoughtful safety procedures, trained flight crews, and advanced airport wildlife management programs, such events are rarely dangerous. The fact that Flight 1727 returned safely without injuries to passengers or crew shows the strength of aviation safety protocols in action.
As airports continue to evolve in how they mitigate wildlife risks and implement advanced surveillance and management techniques, the frequency and impact of incidents like the coyote strike United Airlines flight are likely to decline. For travelers and aviation professionals alike, this event highlights both the unpredictable nature of wildlife encounters and the industry’s capacity to adapt and respond effectively.
