Asiana 214 ver 3
Here is Update 3 of our reconstruction of the Asiana flt 214 crash at San Francisco International Airport on 7/6/13.
As mentioned earlier this a work-in-progress project with updated versions being posted periodically as new information and data become available.
The purpose of this project is to make available to our viewers and the public the most detailed and accurate visual reconstruction of the event possible considering the information available at the time of each new update. We will offer no opinions as to the cause of this accident but hope that our animated reconstruction will encourage discussion and dialog amongst you our viewers.
Here are the main changes made in ver. 3:
Runway 28L threshold displaced 300' further to the west. This is not shown in the latest Google Earth Pro imagery of the airport which was used in the 1st two versions of the reconstruction.
Water vapor shown being blown into the air for the 3 seconds prior to impact. This was most likely caused by the jet blast of both engines as power was applied for the 3 seconds prior to impact and the high angle of attack during that period of time. This vapor can be seen in the Fred Hayes eyewitness video.
Left engine separation and post impact travel. As was correctly noted by a number of our viewers the left engine ended up on the right side of the runway and not the left as shown in ver. 2. The engine likely separated from the aircraft at the moment the fuselage pancaked onto the runway and since full power had been applied just before impact it is very likely that the engine was still developing significant power at the moment of separation and perhaps even continued to produce power for a moment after separation while the fuel still in the engine fuel system was consumed. In a later aerial photograph we obtained there is clear evidence on the runway (scrape marks) that the engine actually passed the aircraft and followed a curved path in front of the nose ending up on the right side of the runway and igniting a grass fire in that area.
A split screen animation will also be posted later today illustrating the cockpit or pilot's perspective from this same reconstruction. We'll post a Tweet from our Twitter account as soon as it's uploaded. Be sure to follow us @EyewitnessAnimations.
Thanks!
