A United Airlines flight from Denver to Los Angeles diverted to Salt Lake City on Thursday after the plane’s cockpit sustained a cracked windshield, according to the airline and the National Transportation Safety Board.

United Airlines flight 1093, from Denver International Airport to LAX, took off around 5:50 a.m. While flying near Moab, UT, the cockpit suffered a broken windshield, according to a NTSB posting on social media platform X.

Pilots immediately diverted the Boeing 737-8 northward and it “landed safely in Salt Lake City to address damage to its multilayered windshield,” a United spokesperson said in an emailed statement.

“We arranged for another aircraft to take customers to Los Angeles later that day and our maintenance team is working to return the aircraft to service,” the spokesperson said.

134 passengers and six crew members were on board. It is unclear the extent of the windshield’s damage and any injuries.

The windscreen was sent to NTSB laboratories for examination, according to transportation officials.

“Aircraft windshields are designed to function safely in case any layer sustains damage,” United officials said.

It is unclear how the Federal Aviation Administration is involved, if any, in the investigation, amid the current government shutdown.

Following the diversion, passengers later boarded a flight to LAX after a roughly six-hour delay, according to flight tracker FlightAware.

The cracked windshield remains under NTSB investigation.
