韩国韩亚航空公司的波音777客机6日在美国旧金山机场降落时坠毁，但机身保持完好，众多乘客从破损的飞机内成功逃生。据报道至少两人死亡。
美国联邦航空管理局发言人称，失事客机本应在28号跑道左侧着陆，但不知何故突然在落地后发生事故，并冒起了浓烟，乘客纷纷通过充气滑梯上逃出机外。从现场画面看，失事客机尾翼脱落。
韩亚航空是韩国第二大航空公司，与美洲航空公司和英国航空公司是合作伙伴。
失事的波音777-200客机是一种远程宽体飞机，配有两个引擎，是一种非常受国际市场欢迎的远程客机，能搭载246～300名乘客。
美国上一次大型客机坠毁事故发生在2001年，当时，一架从纽约肯尼迪机场起飞的空客300飞机升空后坠毁，机上人员全部遇难。此后，美国也发生过一些小型客机失事坠毁事故。

SAN FRANCISCO 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 spokeswoman Lynn Lunsford says the Boeing 777 crashed at San Francisco Airport while landing on Saturday.
Asiana Flight 214 was arriving from Seoul.
Photos and video of the aircraft show fire and smoke from the aircraft.
Early reports indicate the tail came apart from the plane and the resulting fire sent black smoke billowing into the air, visible for miles.
CBS Station KPIX reports witnesses heard a loud bang, and saw a huge cloud of smoke.
Rescue vehicles were on the scene immediately afterwards.
The airport has been closed -- no flights were being allowed in or out of SFO at this time.
