A Newark-bound Southwest Airlines flight made an emergency landing in Cleveland on Wednesday after a window cracked.
Photographs taken by a passenger on Southwest Airlines flight WN957, which took off from Chicago Midway International, show a broken window next to a row of passenger seats.
A portion of the window's glass appeared to be missing.
Southwest issued a statement saying that the plane's flight crew "made the decision to divert the plane to Cleveland for maintenance review of one of the multiple layers of a window pane."
"The flight landed uneventfully in Cleveland," the statement read.
An airline spokesperson said that the aircraft has since been taken out of service for a maintenance review.
The airline said it was working to reaccomodate the flight's 76 passengers.
Another passenger reported that the cracked window, located at an emergency exit, shattered mid-air, according to Dans Deals.
Southwest has been embroiled in controversy since a woman was killed after one of its plane's engines exploded, and shrapnel from the engine shattered a window.
Wells Fargo executive Jennifer Riordan, 43, died after she was partially sucked out of the broken window.
Wednesday's incident draws renewed attention to the airline's aircraft maintenance issues.
