- A transatlantic United Airlines flight was diverted around an hour into its journey on Sunday.
- An airline spokesperson told BI the Boeing 787 had a crack in its windshield.
A United Airlines plane heading from Denver to London was diverted on Sunday due to a crack in its windshield.
The Boeing 787 Dreamliner changed course about an hour into a transatlantic flight, data from Flightradar24 shows. It landed at Chicago O'Hare around one hour later.
A spokesperson for United told Business Insider that the plane "landed safely in Chicago to address a crack in one layer of its multilayer windshield."
They added that the airline booked passengers into hotels overnight and rebooked them on other flights to London the following day.
FAA aircraft registry information indicates that the Boeing 787 involved was registered eight years ago.
This isn't the first Dreamliner to suffer a cracked windshield in recent months.
In December, a Norse Atlantic plane managed to safely continue on between Orlando and London in a similar incident, Simple Flying reported. It took 50 hours to repair the plane.
For United Airlines, Sunday's incident is the latest in a string of events that has seen it come under increased scrutiny from the Federal Aviation Administration.
In March, the carrier's vice president of corporate safety told employees that regulators were increasing scrutiny of United.
Bloomberg reported that the FAA was blocking United from approving or promoting pilots to fly different plane models and that more drastic actions, such as preventing it from adding new flight routes, were also being considered.
That came after incidents of maintenance flaws, like a tire coming off a Boeing 777.
Last Friday, another transatlantic United flight had to turn around after one of its toilets malfunctioned and started leaking into the cabin.
