The flight landed safely in Memphis and taxiied back to the gate. United allocated another aircraft to the flight, and it ended up departing several hours later. The aircraft, meanwhile, remains on the ground and will need repairs before it can reenter service. Simple Flying reached out to United Airlines for further information, but a representative was not immediately available for comment.
A Cracked Windshield And A Diversion
United Airlines flight UA1126 is a daily service between Memphis International Airport and Chicago O’Hare International. This flight number is also used on flights between Chicago and Newark, and from Newark to Tampa. On December 1, the leg from Memphis to Chicago was being operated by N14735, a 26-year-old Boeing 737-700. It’s unknown how many passengers were onboard, but the jet has a capacity of 126 seats, and would require two pilots and three flight attendants.
UA1126 departed Memphis at 7:34 am, only four minutes behind its scheduled departure time. It was scheduled to arrive at 9:26 am, with a block time of one hour and 56 minutes. As the aircraft was climbing through 13,000 feet, the windshield on the First Officer’s side of the aircraft developed a crack. The severity of the damage is unknown, likewise whether this was an issue with the aircraft itself or the result of a collision with a bird or an object.
The crew declared an emergency and began descending while turning back towards Memphis International Airport. UA1126 landed on Memphis’s Runway 36R after roughly half an hour in the air. The flight was able to taxi to the gate on its own power, and no injuries were reported.
The Aftermath Of The Incident
UA1126 landed safely at Memphis International Airport and taxiied to its gate. Passengers were deplaned, and United sourced a replacement 737. The new aircraft was N81449, a 179-seat Boeing 737-900ER. The aircraft was coming into Memphis from Washington-Dulles, and as such, UA1126 wouldn’t depart Memphis again until 2:04 pm.
The aircraft arrived at Chicago-O’Hare at 3:25 pm, resulting in a roughly six-hour delay. Passengers were likely compensated for the delay, and United would have also needed to rebook connecting passengers on alternative flights. As Chicago-O’Hare is United’s largest hub, this wouldn’t have been too difficult for the carrier.
N14735 is still on the ground after the incident. A crack in the windshield could potentially lead to a pressurization issue, and as such, the aircraft will need to be repaired before reentering service. United will either need to ship replacement parts to Memphis for the repairs, or the 737 will need to be ferried to a nearby maintenance base (likely Chicago-O’Hare). Due to the pressurization issue, N14735 will need to be flown at a lower altitude if the carrier decides to fly it to another facility.

The incident certainly is a cause for concern.
Why Is The Windshield Crack An Issue?
Perhaps the most obvious problem with a cracked windshield is that this can greatly reduce visibility for the impacted pilot (in this case, the First Officer). However, airline pilots primarily rely on instruments to fly. Perhaps more importantly, a cracked windshield can cause depressurization in the cabin.
United has not confirmed the extent of the damage to the windshield, but a crack in the windshield has the potential to spread and cause more damage to the glass. Not only would this increase the rate of depressurization, but damage to the windshield could injure the pilots.
In October 2025, a United 737 collided with an object in midair, causing the windshield to shatter. It is believed that a weather balloon struck the aircraft, and this caused glass shards to fly into the cockpit, causing minor injuries to one of the pilots.
