A United Airlines flight from LA to Denver lost a wheel during takeoff Monday morning, the airline confirmed.

A United Airlines flight traveling from Cancun to Chicago was diverted to Memphis, Tennessee, after the plane encountered "a brief period of severe turbulence" that left one passenger hospitalized and six others injured, officials say. 

The aircraft, a Boeing 737-900, landed safely at Memphis International Airport around 2:50 p.m. Wednesday, the Federal Aviation Administration (FAA) told FOX Business. 

"United Flight 1196 diverted to Memphis [Wednesday] afternoon after encountering a brief period of severe turbulence while the seatbelt sign was on," the airline said in a statement. "Paramedics met the aircraft at the gate and transported one passenger to the hospital.  

"We’re grateful to our crew for their efforts to ensure the safety of our employees and customers," it added.

The Memphis Fire Department told FOX Business that "six people declined treatment and transport" to a hospital while "the extent of their injuries is unknown."

The incident comes as a study by the University of Reading in the U.K. has found that clear-air turbulence has increased in regions around the world. Over the North Atlantic, which is one of the busiest flight routes, the total annual duration of severe turbulence increased by 55% between 1979 and 2020.

Moderate turbulence increased by 37%, and light turbulence increased by 17%. All the increases were consistent with the effects of climate change, according to the study, which was published in Geophysical Research Letters.
