There are no injuries and the 172 passengers are deplaning via airstairs. Passengers got off the plane using air stairs that are pulled to the aircraft, the aviation safety agency said.

Southwest Airlines continues to make headlines after a pickup truck slammed into one of its planes in Baltimore early Monday.
The sales of air tickets took a plunge for Southwest Airlines following the horrifying incident, costing the company between $50 million and $100 million in losses. Flight 1118 had left Nashville International Airport around 8:30 p.m., and was supposed to land at Dallas Love Field.
The carrier operated Florida One, Southwest's Boeing 737-700 emblazoned with an artist's rendering of the state flag on the inaugural flight on May 6. The blast sent debris flying into the plane, breaking a window and killing a passenger. Riordan was nearly sucked out of the window, but was saved by her co-passengers.
