So what I'm gathering from this animation is that, if they hadn't crashed, they would have landed...

So I too gather. But only IF they(pilot/s) had ......

I am with PhotoFinish, flawed animation is like flawed news, they have no business being published for they distort the trugh and adds to the confusion. Drop it.

Video needs to be corrected for a few flaws, Left engine apparently ended up on the right side of Runway 28L, Fire started after the airplane came to a rest on the dirt.

Can there be a way for the guys at FA to it possible to check or align the blogs on time scale like newest first and so on?

Here's another short video from the same poster, with the cockpit perspective.

The saying is lies, damn lies and statistics. Apparently you can add animations to the list now.

The sensationalistic use of flames all over the fuselage many minutes aged of reality, as well as the inaccurate track of the engines are the least of this animation.

The animation is severely out of scale. Asiana dropped below the glidepath long before the point indicated in this animation.

Asisna 214 had 3 red PAPI at 500 ft (when the pilot flying alleged he say the bright light.) The plane continued to drop further below the glidepath, and would be well below 4 red PAPI at 100 ft, yet this animation shows Asiania 214 close to altitude of the plane representing the proper glidepath altitude over the light pier at the very end of the approach, immediately before the seawall of the runway.

It would be more useful for the animation to track the Asiana flight from DUVET where it was above the glidepath (2200 vs. 1800 ft) showing not only the steeper descent, but the insufficient and late reaction to the plane dropping below the glidepath. Also, the animation could show the change in attitude of the plane as they pulled the nose up slightly to reduce the descent, as well as the resulting severe reduction in speed that was causing the plane to stall out. The the last minute attempt to avoid the light piers/ seawall by raising the nose and finally pushing the thrust forward too late to avoid the ground.

If would be interesting to see the whole picture. It might help people to associate the Asiana incident to another example scenario that non-aviators might find easier to relate.

That being, traveling down one hill in a car at slow speed with the intention of coming to a complete stop at the flat stretch at the bottom of the hill (with the foot off the accelerator pedal and the engine merely in idle) then reaching the bottom and suddenly needing to go up the next hill instead to avoid a collision with a huge boulder in your lane, but even pushing the gas pedal to thd floor, unable to get the heavily loaded vehicle moving at full highway speed fast enough up the next hill before that tractor trailer in the next lane plows through you. Also add to the picture that your engine takes at least 7-9 seconds to get up to full power.

That 18 wheeler might have brakes, but the last time I checked gravity doesn't. So trying to pull a heavy plane out of a fall at the last minute (below 100 ft) with the planes' engines in idle is not easy, and likely impossible due to the laws of physics, with all that downward momentum of such a heavy plane, and the inertial resistance to get a large engine spinning up at full speed, which will take time in the best of curcumstances.

The car on hill analogy aside, this Asiana animation could benefit from showing a longer perspective of relative glidepath position vs. normal, as well as the insufficient futile attempts to change the certain crash at the last minute.

But the positions need to be more accurate. Better than within 100 ft (as flight aware data shows position only to the nearest 100ft) when the animation is showing the flight below 100 ft. Assuming the animator is using public flightaware data, the error is as large the altitude bring illustrated. Showing the descent starting from a much higher altitude allows to better plot the descent because of more data points available to mote accurately show the path.

Nobody said it was perfect. You are a hell of a lot more correct on the animation, and yeah, they should have started it at DUVET to give non aviators a truer picture of just how bad they did screw up. I really don't think people realize just how bad they did screw up for whatever reason.It doesn't back out that far, but Marcus has posted one from later that is a little more accurate. Preacher1

Thanks.

I don't expect perfection either, though, earlier in the day, the description did state that the animation was entirely accurate.

The creator does seem interested in correcting mistakes. And he now acknowledges that the reference plane speed is completely incorrect and would fly off the screen very quickly.

But watching the plane burn up on impact just seemed wrong on so many levels. We would've been lucky to have had 2-3 severely burned survivors if the plane was completely engulfed in flames before even coming to a complete stop, instead of having 3 casualties and numerous severe injuries, like has happened thus week.

Seems that he'll continue to make it better as evidenced by the newer version.

But so far the animation is inadequate in showing how badly this crew screwed up. (Though I did enjoy watching it, and look forward to future improvements.)

A non aviator speaks!
How right you both are. And fairly good teachers, at least for guys like me. I hope there are some more guys(means gals too) on this portal who blog in such a way that both categories are satisfied, the 'true' aviators and the non kind!
In case you know the animation business or can take help. will you please try to make a comprehensive animation, class room instruction style. Am I asking for too much? If yes, my apologies. But request stands.

There is a link above that Marcus posted that is a little more accurate, although as Photo Finish said, it doesn't start near as far back as it should.

Ken's post at the bottom to the mashable link, provides not only the v2 video, but excellent background info about the 727 pilot 3D artist putting these together.

It also informs about a promise to have a couple of new vids up by Monday afternoon with different perspectives, including one chaser view showing the reference plane pulling far ahead.

Well than maybe you should handle that PhotoFinish, Geez wow ...

Airline Pilot Creates Realistic Animation of Flight 214 Crash

An airline pilot used available information to create a video of 214's actual approach as well as a ghost image of what it's approach should have been.

Here's something that has not come up in other discussions. The NTSB mentioned 214 was right of center. But that turned out to be a good thing given he would have taken out the approach lights.
