Houston U-Turn As United ERJ-175 Windshield Shatters

A United Express Embraer ERJ-175 returned to Houston shortly after departure when the first officer’s windshield shattered during the climb.
Mesa Airlines operated the aircraft on behalf of United as flight UA6309 to El Paso, Texas, with 72 people on board.
The crew landed safely back at Houston Intercontinental Airport around 35 minutes after takeoff.
What Happened After Departure From Houston
The ERJ-175, registration N87360, departed from runway 15R at Houston Intercontinental and began a normal climb towards El Paso.
However, the crew stopped the climb at around 13,000 feet.
The pilots then reported that the right hand windshield had shattered.
According to the crew, the damage did not stop at a single layer.
Instead, pieces of glass began falling into the cockpit.
As a result, the pilots levelled off, worked through the situation and decided to return to Houston.
No Loss of Pressurisation
The airline later confirmed that the first officer’s windshield had shattered.
Importantly, it also stated that the aircraft did not lose pressurisation at any stage of the flight.
That detail explains why the event ended calmly. Airliner windshields use several laminated layers of glass and plastic bonded together.
Because of this design, one layer can fail while the remaining layers continue to carry the pressure load.
In this case, the structure held, although glass fragments still entered the flight deck.
Loose glass in the cockpit still presents a real hazard.
Small fragments can distract the crew, affect their vision or interfere with controls and switches.
Therefore, an immediate return to the departure airport was the sensible choice.
Safe Landing Back at Houston
The crew flew the aircraft back to Houston and landed safely on runway 09.
The landing took place around 35 minutes after the original departure from runway 15R.
Returning to Houston also made practical sense for the operator.
Houston Intercontinental is a major United hub, so the airline had engineering support and spare aircraft close at hand.
Consequently, the recovery of the flight could begin almost immediately.
Passengers Reach El Paso on a Replacement Jet
Meanwhile, United and Mesa arranged a replacement aircraft to complete the journey.
Another Embraer ERJ-175, registration N87339, operated the service to El Paso. Passengers eventually reached their destination around four hours behind schedule.
A delay of that length is frustrating for travellers.
Nevertheless, a four hour disruption compares well with the alternative of an overnight cancellation.
The quick swap reflects the depth of the United Express fleet at its Texas hub.
N87360 Remains on the Ground in Houston
The occurrence aircraft remained on the ground in Houston around 23 hours after landing.
Engineers will need to remove and replace the damaged windshield before the jet can return to service.
In addition, they are likely to inspect the frame, seals and heating connections around the affected panel.
Windshield failures are not rare across the industry.
Cracks can follow bird strikes, hail or faults in the electrical heating that keeps the glass clear of ice.
However, the cause of this failure has not yet been confirmed. The airline has not released any further details on what led to the damage.

The flight path of UA6309 is also available on Flightradar24.
What Comes Next
For now, the incident stands as a textbook example of a crew handling a windshield failure calmly and safely.
The laminated design did its job, the cabin stayed pressurised and the aircraft landed without further drama.
The Aviation Hub will continue to follow this story and will provide updates as more information becomes available.
