United Boeing 737 Damaged by Suspected Space Debris Collision

A United Airlines flight experienced a concerning incident when its windshield cracked after what is believed to be an impact with possible space debris. Thankfully, the crew managed to safely land the aircraft without serious injuries to any of the 140 passengers and crew members. This event may mark a significant first, as authorities suggest it could be the inaugural case of space debris striking an aircraft.

The affected flight, a United Boeing 737 MAX 8, took place on October 16, 2025. This particular aircraft, identified as N17327, was flying from Denver (DEN) to Los Angeles. At approximately 36,000 feet and about 180 nautical miles southeast of Salt Lake City, Utah, the plane was hit by an unidentified object, shattering the cockpit’s windshield and showering glass fragments inside.

Fortunately, the aircraft’s outer windshield layer sustained the damage while the crew opted to divert to Salt Lake City Airport (SLC) as a precaution. They descended to 26,000 feet before ultimately landing safely at SLC around 50 minutes after they initially left their cruising altitude.

Passengers aboard flight UA1093 were transferred to a backup Boeing 737 MAX 9 to continue their journey, arriving in Los Angeles with a delay of nearly six hours.

Images shared on social media depict the extensive damage to the aircraft’s windshield, with the co-pilot’s side completely shattered and an impact point visible in the upper right corner. There are also signs of scorching on the glass, hinting that the cause may be related to space debris or a meteorite. Internal photos even reveal a bloodied arm belonging to one of the pilots.

Based on the damage viewed in these images, many observers speculate that the impact was likely from a solid object, rather than a failure of the windshield itself. While bird strikes or foreign object debris are common at lower altitudes, the prospect of a commercial aircraft being hit at 36,000 feet is almost unheard of.

Currently, airline officials and authorities aren’t dismissing alternative explanations but are primarily considering the theories surrounding space debris or a meteorite impact. Some have proposed that electrical arcing could have caused the scorch marks seen in the photographs, while others consider the rare possibility of hailstorms occurring at such high altitudes.

If it is confirmed that an actual piece of space debris struck the plane, it would herald a historic moment in aviation, being the first known incident of its kind involving a commercial airliner.

As reported, the aircraft remained grounded in Salt Lake City for three days while undergoing repairs before returning to service on a flight from Salt Lake City to Chicago as US 3864. During this downtime, investigators focused on the damage incurred and sought to understand the circumstances surrounding the incident.

The Boeing 737 MAX 8, identified as N17327, is relatively new, having been delivered to United Airlines just 22 months prior in December 2023. It is constructed to accommodate up to 166 passengers, divided between business and economy classes.

Historically, the Federal Aviation Administration (FAA) has deemed the likelihood of space debris impacting a commercial airliner as minimal, indicating a one-in-a-trillion chance of injury to passengers resulting from such an event.

Have you ever wondered how common encounters with space debris are for commercial flights?
