A United Airlines flight from Denver to Los Angeles was forced to divert to Salt Lake City after its windshield cracked midair. The NTSB is investigating the Boeing 737-8 incident as safety concerns rise amid recent airline disruptions.
The National Transportation Safety Board (NTSB) confirmed on Sunday, October 19, that it is investigating the case involving United Flight 1093, a Boeing 737-8 aircraft. The agency stated it is collecting radar, weather, and flight recorder data to determine what caused the multilayered windscreen to fracture during flight. The damaged windscreen has since been sent to an NTSB laboratory for further examination.

What Happened During the Flight
According to United Airlines, the incident occurred on October 16, when pilots detected a crack in one of the windshield layers mid-flight. Following protocol, they decided to reroute the aircraft to Salt Lake City International Airport (SLC) as a safety precaution.
The flight carried 134 passengers and six crew members, all of whom landed safely without further complications. Another aircraft was promptly arranged to transport passengers to Los Angeles International Airport (LAX) later that same day.
Photos shared on social media show significant damage to the cockpit’s front window, with one image appearing to show a pilot’s arm with visible cuts, though officials have not confirmed the extent of any injuries. United Airlines later emphasized that aircraft windshields are designed with multiple layers, allowing them to withstand pressure and remain operational even if one layer is compromised.

NTSB and Ongoing Investigation
In a post on X (formerly Twitter), the NTSB stated:
“Operating as United Flight 1093 from DEN to LAX, the airplane diverted safely to SLC. NTSB gathering radar, weather, flight recorder data. Windscreen being sent to NTSB laboratories for examination.”
The preliminary investigation suggests the crack may have formed near Moab, Utah, but officials have not yet confirmed the cause. Boeing and United maintenance teams are cooperating with federal authorities to assess whether structural stress, weather, or debris impact may have contributed to the incident.

Other United Airlines Incidents
The cracked windshield came just a day before another unrelated event involving two United Airlines aircraft that made contact on the tarmac at Chicago O’Hare International Airport. One plane’s wing reportedly clipped another’s stabilizer during ground operations. Fortunately, no injuries were reported in that case either.
These incidents occur amid broader aviation challenges, including a partial government shutdown that has led to delays across major airports as TSA officers and air traffic controllers continue working without pay.
Despite these disruptions, United Airlines emphasized that safety remains its top priority and that it is fully cooperating with federal investigators to ensure the issue is properly addressed before the aircraft returns to service.
Frequently Asked Questions (FAQs):
1. What caused the cracked windscreen on the United Airlines flight?
The cause is still under investigation by the NTSB. The board is analyzing radar, weather, and flight data, along with the damaged windshield, to determine the source of the crack.
2. Were any passengers or crew injured?
United Airlines reported no passenger injuries. Some unconfirmed reports suggested a pilot sustained minor cuts, but this has not been officially verified.
3. What type of aircraft was involved?
The incident involved a Boeing 737-8 (737 MAX 8) aircraft operating as United Flight 1093 from Denver to Los Angeles.
4. How common are windshield cracks on planes?
While rare, minor windshield cracks can occur due to temperature changes, pressure shifts, or debris impacts. Commercial aircraft are designed to withstand such damage safely.
5. What happens when a flight diverts due to technical issues?
When pilots detect potential risks, they follow emergency diversion protocols to land at the nearest safe airport. Passengers are then transferred to another aircraft to continue their journey.
