Mystery Object Strikes United Airlines Aircraft Over Utah
A United Airlines flight en route from Denver to Los Angeles experienced a mid-flight incident on Thursday when an unknown object struck the aircraft’s windscreen. The National Transportation Safety Board (NTSB) has launched an investigation into the event, which resulted in damage to one of the cockpit windows and minor injuries to a pilot. The incident has sparked speculation about the nature of the object, with initial reports suggesting the possibility of space debris.

NTSB Investigates Windscreen Strike
The NTSB confirmed on social media platform X that it is actively gathering data related to the incident. This includes radar information, weather conditions at the time of the strike, and flight recorder data from the aircraft. The damaged windscreen has been removed and sent to NTSB laboratories for thorough examination. The agency’s investigation aims to determine the precise cause of the impact and identify the object involved.
The affected aircraft, a Boeing 737 MAX, was diverted to Salt Lake City International Airport following the incident, where it landed safely. Images circulating on social media depict significant cracking on one of the two large windows at the front of the aircraft. Furthermore, images show what appears to be minor cuts on the arm of one of the pilots, potentially caused by small shards of glass from the damaged windscreen.
Pilot Speculates on “Space Debris”
According to initial reports, the flight’s captain described the object that struck the plane as “space debris.” However, this assessment remains unconfirmed by official sources. While the possibility of space debris cannot be immediately ruled out, investigators are considering a range of potential causes. The aircraft was flying at an altitude above 30,000 feet, likely around 36,000 feet, at the time of the impact.
The location and altitude of the incident raise questions about the types of objects capable of reaching such heights. While some bird species can fly above 30,000 feet, the world’s highest-flying bird, Rüppell’s vulture, is primarily found in Africa, making it an unlikely culprit. Other possibilities include an unregulated weather balloon, although the velocity required to cause the observed damage may be a limiting factor. Hail is also being considered as a potential cause.
Meteorite vs. Space Debris: A Question of Probability
While the pilot’s initial assessment focused on space debris, statistical probabilities suggest that a meteorite is a more likely cause. According to a study published in the journal Geology, an estimated 17,000 meteorites strike Earth each year. This figure is significantly higher than the estimated amount of human-made space debris that survives reentry into Earth’s atmosphere. It is important to note that space debris includes defunct satellites, rocket parts, and other man-made objects orbiting Earth.
The forceful impact near the upper-right part of the window, as evidenced by damage to the metal frame, underscores the intensity of the collision. The multilayered construction of aircraft windows, incorporating laminate layers, prevented a complete shattering of the pane and maintained cabin pressure. A careful analysis of the glass and metal impacted by the object will be crucial in determining its composition and ultimately revealing its origin.
Analysis of Damaged Components Crucial
The investigation hinges on a detailed examination of the damaged windscreen and surrounding structures. Experts will analyze the materials to identify any traces of the object that caused the impact. This analysis could reveal the object’s composition, density, and other characteristics that would help narrow down the possibilities. Microscopic analysis of any residue or embedded particles could provide crucial clues.
Furthermore, the NTSB will review radar data to identify any unusual objects or atmospheric phenomena in the vicinity of the aircraft at the time of the incident. Weather patterns and atmospheric conditions will also be carefully examined to assess the likelihood of hail or other weather-related events. The flight recorder data will provide a detailed record of the aircraft’s altitude, speed, and heading, which could help pinpoint the exact location of the impact and rule out potential causes.
Conclusion: Awaiting Definitive Findings
The investigation into the United Airlines windscreen strike remains ongoing. While initial speculation centered on space debris, the NTSB is considering all potential causes, including meteorites, weather balloons, and even hail. The analysis of the damaged windscreen and the collection of radar, weather, and flight recorder data are crucial steps in determining the nature of the object and preventing similar incidents in the future. The NTSB’s findings will provide valuable insights into the risks posed by both natural and man-made objects in the airspace.
