On Saturday, just before noon, an Asiana Airlines flight from Seoul hit the sea wall protecting San Francisco International Airport from the surrounding bay. The Korean pilot — trying to land a Boeing 777 for the first time at SFO, manually — had the plane flying too slow and too low. His apparent attempt to abort the landing for another go was too late, and the tail end of the aircraft hit the wall, sending the rest of the plane skidding 2,000 feet along the runway. Two teenage girls died.

As seems to happen these days, somebody captured the crash on video. Self-described "aviation buff" Fred Hayes had his camera in hand in the right place at the right time to catch the Korean jetliner go down — as a woman in the video notes. Hayes immediately sees that the plane is too low and its nose is too high. Then he says "Oh my god" — a lot. Watch above.
