CNN — "Look at that one -- look at how his nose is up in the air."
The big Boeing jetliner looked a bit odd to aircraft buff Fred Hayes as it neared the runway at San Francisco International Airport. It seemed to be low, and its nose was tilted sharply upward.
Then a banging sound echoed across the water, and the jet flipped nose-down and skidded in an orange-and-gray cloud. Hayes captured the scene on video while on a walk with his wife along San Francisco Bay, about a mile away.
"Oh, my God," Hayes said as Asiana Airlines Flight 214 tore into the tarmac and skidded across the ground. "Oh my God. Oh, my God. Oh, lord have mercy."
The crash-landing left two dead and hurt 182 people, six of whom were in critical condition Sunday. But 123 others walked away unhurt.
Hayes told CNN's Don Lemon on Sunday that the Boeing 777 "maybe a little lower than some of the other planes" as it approached, "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," he said "As you can see in the video, it was pretty low at that point and that may or may not have been the case."
That squares with what investigators from the National Transportation Safety Board reported Sunday afternoon. Asiana 214 appeared to be too low and too slow as it neared the runway, and the cockpit voice recorder indicates the crew tried to abort the landing less than two seconds before the crash, NTSB Chairman Deborah Hersman told reporters.
Aviation expert Jim Tilmon called the video is "remarkable footage" that will likely be analyzed by investigators "over and over again."
Once the jet hit the ground, it skidded nose-down and sideways, spinning counterclockwise and catching fire. Tilmon, a former jetliner pilot himself, told CNN the pilot showed "a fair amount of skill" in keeping the jet from flipping over.
"If that had happened -- my goodness, this would be a completely different kind of report to make today," he said. "Because there would sure have been a great deal more injuries as a result."
Hayes said he and his wife watched as the emergency slides deployed and passengers began to slide down them away from the wrecked jet.
"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," he said.
