Sheryl Sandberg, Facebook's chief operating officer and author of the book "Lean In," was supposed to be on Flight 2014. But she switched to a United flight, arriving about 20 minutes before the Asiana flight crashed.
"Serious moment to give thanks," she wrote on her Facebook page
Not the first time
Prior to Saturday's disaster, Asiana Airlines endured two deadly crashes over the past 20 years.
In 1993, a crash near South Korea's Mokpo Airport killed 68 of the 116 people on board. The Boeing 737-500 went down in poor weather as the plane was attempting its third landing, the Aviation Safety Network said.
And in 2011, a cargo plane headed from Seoul to Shanghai slammed into the East China Sea, killing the only two people on board.
Perhaps one of the reasons so many people survived Saturday's crash was because the Boeing 777 is built so that everybody can get off the plane within 90 seconds, even if half the doors are inoperable.
Still, many questions linger.
Yoon, Asiana's president and CEO, told reporters he could not confirm many details of the crash, pending the investigation.
But he started the press conference by bowing his head in apology.
