Pilot Injured, Plane Grounded: Was a United Jet Struck by ‘Space Debris’ at 36,000 Feet?
SALT LAKE CITY, UT—A routine cross-country flight on United Airlines took a bizarre turn last week when the cockpit windshield of a Boeing 737 MAX 8 cracked at cruising altitude, injuring one of the pilots and forcing an emergency diversion. The unusual nature of the damage has fueled intense speculation among aviation experts that the aircraft may have been struck by something highly unlikely: space debris or a small meteorite.
The aircraft, operating as Flight UA1093 from Denver (DEN) to Los Angeles (LAX), diverted to Salt Lake City (SLC) on Thursday, October 16, 2025. The plane remains grounded days later as federal investigators try to solve the mystery.
The Incident at 36,000 Feet
The incident occurred about 30 minutes into the flight while the aircraft, carrying 140 passengers, was cruising at 36,000 feet over Utah.
- The Damage: The crew reported a cracked windshield, which, according to images shared by aviation insiders, showed unusual scorch marks and severe internal fragmentation.
- Pilot Injury: One of the pilots sustained bruising and abrasions on his arm, consistent with being struck by shattered fragments of the multi-layered glass.
- Emergency Protocol: The flight crew immediately descended the aircraft to 26,000 feet to manage the cabin pressure differential before making a safe landing at Salt Lake City International Airport (SLC) approximately 50 minutes after the initial impact.
The Space Debris Theory
The presence of scorch marks and the extreme altitude of the incident have ignited theories that the jet was struck by debris from space. While experts acknowledge the likelihood of a commercial jet being hit by a meteor fragment or human-made space junk is infinitesimally low—estimated at less than a trillion-to-one chance of causing a casualty—the unique damage signature has complicated the investigation.
Normally, windshield cracks result from benign factors like manufacturing stress or temperature changes, or from hail/bird strikes at lower altitudes.
Passenger Disruption and Ongoing Investigation
The damaged Boeing 737 MAX 8 (registration N17327), which is less than two years old, was immediately taken out of service. United quickly dispatched a replacement Boeing 737 MAX 9, but the passengers still endured a delay of approximately six hours before continuing their journey to Los Angeles.
The Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) are now investigating. Their focus will be on eliminating less exotic causes—such as an electrical malfunction in the windshield’s heating system—before drawing any final conclusions on the potential external object strike. The aircraft remains in Salt Lake City as a full forensic inspection is carried out.
Conclusion
United Flight UA1093’s emergency diversion is a highly unusual case that pushes the boundaries of known aviation safety threats. The quick-thinking crew successfully averted disaster, and the aircraft’s integrity held up, but the lingering question of what struck the plane at high altitude now rests with federal investigators. The findings of this NTSB inquiry could lead to new insights into the potential risks posed by high-altitude foreign object strikes in an increasingly crowded airspace.
