This animation recreates Saturday's Asiana Airlines Flight 214 crash at San Francisco International Airport. Jack Suchocki, a former pilot who now runs an Eyewitness Animations, created the video. While the video is a simulation of events that killed two and injured an estimated 180, the audio communication is real.
In detail, Suchocki points out:
All times, speeds, distances and scaling contained are accurate to the data available as of July 10, 2013. There is also included in the segment a blue transparent exemplar aircraft programmed to follow the correct 3 degree glide slope to the intended touchdown point 1,000 ft down the marked runway. This is the path and altitude the Asiana flight should have been flying during the approach. Please note that the blue exemplar aircraft is not programmed to fly at the correct approach speed, only the correct altitude. If it were programmed to fly the correct approach speed it would very quickly pass the Asiana aircraft and disappear off screen. The reconstruction also contains the actual SFO tower communications with flight 214 although the actual timing of the communications may not be absolutely synchronized to the animation since the data necessary to precisely synch won't be available until it is released by the FAA or NTSB in the coming weeks.
