A Boeing 777 operated by Asiana Airlines crashed while landing at San Francisco International Airport on Saturday, according to the Federal Aviation Administration.

The airplane was coming in from Seoul, South Korea and apparently crashed sometime after touching down on Runway 28. No other details were immediately available.

Firefighters were at the scene of the crash and thick clouds of black smoke were billowing from the grounded aircraft as people escaped on emergency slides, reported RT.

People were reportedly trapped inside the aircraft, according to a police scanner, after the “whole tail came off.”
