Update 2 reflecting no initial post-impact fire.
This is a very accurate reconstruction of the crash of Asiana flight 214 at
San Francisco Airport on July 6, 2013 with the exception of the post impac
t fire. It is now reported that the fire did not break out until 90 seconds
after the aircraft came to rest. That adjustment will be made and re-poste
d this evening.
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 blu
e transparent exemplar aircraft programmed to follow the correct 3 degree g
lide 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 du
ring the approach. Please note that the blue exemplar aircraft is not progr
ammed to fly at the correct approach speed, only the correct altitude. If i
t were programmed to fly the correct approach speed it would very quickly p
ass the Asiana aircraft and disappear off screen. The reconstruction also c
ontains the actual SFO tower communications with flight 214 although the ac
tual timing of the communications may not be absolutely synchronized to the
animation since the data necessary to precisely synch won't be available u
ntil it is released by the FAA or NTSB in the coming weeks.
This reconstruction will continue to be further refined and re-posted as ne
w data becomes available.

Very interesting. If the audio timing is correct, it is pretty amazing the electrical system and COM radios were still working after such a violent impact sequence. I guess if the antennas were sheared off, they were close enough to the tower for the transmitters to still get through.
Thanks for the data!

The spec I had to meet was a 30g impact with the runway. The radio didn't necessarily have to work afterwards, just not break loose and fly forward.
I've seen working Dell D610 Latitudes that looked like they survived jousting matches.

I was looking for a cheap spare-parts machine, but after seeing what they withstood I decided I don't need one. Later I picked up a trashed, partly stripped D620 for the keyboard and found that its hard drive was still fine.
One of my second-hand hard drives has a large swipe of damage between 9 and 14GB, as though it had been dropped while running, but after partitioning around that area it's error-free.

Not sure how many Gs the impact was, but as everyone survived the impact, i t couldn't have been too harsh. I'm not surprised that the COM radio surviv ed. As for the timing, from the description of the video:
"The reconstruction also contains the actual SFO tower communications with flight 214 although the actual timing of the communications may not be abso lutely 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 com ing weeks."
