At least three people are reported injured after a Southwest Airlines plane skidded off the runway at the Nashville International Airport Tuesday night.

“Southwest Airlines 31, a Boeing 737 aircraft, rolled off a taxiway into the grass and got stuck while taxiing to its gate at Nashville International Airport at 5:30 p.m. Central Time,” according to the Federal Aviation Administration, or FAA. “Passengers left the aircraft via stairs and were bused to the terminal. The flight just landed from Houston Hobby Airport. The FAA is investigating,”

Three ambulances were dispatched to the airport to treat at least three people. Two of those people suffered minor injuries and one person is suffering from chest pains, according to fire spokesman Brian Haas collected from The Tennessean.
