(AP) - A federal aviation official says an Asiana Airlines flight has crashed while landing at San Francisco airport. It was not immediately known whether there were any injuries.
Federal Aviation Administration spokesman Lynn Lunsford says the Boeing 777 crashed at San Francisco Airport while landing on Saturday.
A video clip posted to Youtube shows smoke coming from a silver-colored jet on the tarmac. Passengers could be seen jumping down the inflatable emergency slides.
The airline is based in Seoul, South Korea. Its website says its Boeing 777 can carry between 246 to 300 passengers.
