"Taking a minute to be thankful and explain what happened. My family, colleagues Debbie Frost, Charlton Gholson and Kelly Hoffman and I were originally going to take the Asiana flight that just crash-landed. We switched to United so we could use miles for my family's tickets. Our flicht was scheduled to come in at the same time, but we were early and landed about 20 minutes before the crash. Our friend David Eun was on the Asiana flight and he is fine. Thank you to everyone who is reaching out - and sorry if we worried anyone."

This was the Facebook status of Facebook Chief Operating Officer Sheryl Sandberg an hour after the Asiana Airline flight crash landed. The crash-landing killed 2 Chinese and injured 182 people among the 307 passengers and crew.

According to Variety, Ms Frost is Facebook's director of communications while Ms Hoffman is an administrative assistant. Mr Gholson on the other hand is Facebook's research associate. The team visited Facebook's Tokyo office and luckily had to changed flight.

Mr Eun is Samsung's Electronics executive VP and head of the company's Open Innovation Center. He was one among the passengers who sent out tweets directly from the Asiana Airlines crashed flight. According to Mr Eun, "the experience was surreal" but "most everyone on board seems fines.

In other reports a witness was able to take an amateur video of the crash landing.

In a report from CNN, witness Fred Hayes said that as the plane approach the San Francisco International Airport, "it seemed to be low, and its nose was tilted sharply."

The video showed the plane crash-landing "with a banging sound echoed across the water, and the jet flipped nose-down and skidded in an orange-and-gray cloud."

Mr Hayes, together with his family, was visiting San Francisco and was waiting for the taxiing United Airlines Jet when he witnessed what happened to the Asiana flight.

"Oh my God! Oh My God! Oh, My God. Oh Lord have mercy!" was Mr Hayes initial reaction. "When I caught the plane coming into view, everything looked fine at first until I kind of fixed my gaze on him, and I seen his nose up in the air. And then I just totally locked on him. I thought he was going to take off and go up, and then he just kept going down."

He recalled that the plane "maybe a little lower than some of the other planes, but I couldn't say that for sure."

"My initial thought was that with the nose pitched up in the degree that it was that the pilot was maybe trying to divert the landing... As you can see in the video, it was pretty low at that point and that may or may not have been the case. Every time a section hit, you could hear that boom and that sound... really big booms. It just kind of slid and came to a stop. The only thing we can say is we're just really happy that a lot of people survived, because it wasn't looking good for them folks on that plane for sure."

Another witness Jim Tilton, a former jetliner pilot himself, believed that the pilot of the Asiana Airlines observed "a fair amount of skill in preventing the jet from flipping over."

"If that happened (flipping) - my goodness, this would be a completely different kind of report to make today. Because there would sure have been a great deal more injuries as a result."
