Tough couple of weeks for ROKAF. I'm glad both guys got out safely.

On 22 May 2009, the ROKAF proclaimed the accident cause was human mistake. The accident occurred during a normal training flight to practise climbing at slow speed to lose lift, then recovering the plane just before it stalled.

During the accident, while climbing at slow speed, the trainee pilot in the front seat was late to initiate recovery. The instructor pilot in the back seat recognised their problem, took control, and tried to recover; but speed rapidly dropped, and stalled.
The plane was inverted and uncontrollable at 5,700 m ASL; and the pilots punched out at 1,740 m ASL.

Debris/wreck were salvaged for investigation. Front fuselage and rear wings were damaged, but both wings and fuselage seemed in excellent condition.
Mechanical cause/problem was improbable.

(Yahoo! South Korea News probably has articles, with more details, from the original source Yon Hap News.)

11 December 2009:
Seems this year's ROKAF Top Gun is a Major (40) of 122nd FS, 11th FW, who flies the F-15K, and flew the F-4, F-5, and F-16.
Seems in June 2001, he bailed out of a F-16.

I'm a layman and obviously can't appreciate the pickle the pilots found themselves in but they were more than 3 miles above sea level which strikes me as pretty high up and just maybe enough height to effect a recovery. Or is this situation something that test pilots never tried emulating during the development and testing of the Viper? Could the FCS be programmed to automatically recover from such a scenario? Just curious.

Not a whole lotta specifics there but it sounds like they tried to do a simple approach to a stall and got themselves into an upright deep stall. But in the process of rocking outta that, they may not have arrested the nose falling thru the vertical fast enough and it snapped into an inverted deep stall, which is even scarier than the upright 'cause of the negative G and that wicked spin. Generally the safety rules state that if you haven't recovered and regained control by a set altitude that you must eject. For USAF it used to be 10,000 ft. ASL and may still be. Those guys punched at just under 6000 ASL, so they cut it real close.

Deep stalls have been known about for years and not just in the Viper world. Edwards had (and maybe still does) a program where line pilots went up in a spin chute-equipped jet and flew or were flown into a deep stall so they knew what to do. Not sure if the Eddie techs had to tweak the jet to facilitate the stall entry tho.

We trained both kinds of deep stall recoveries in the sims at Tucson by moving the fuel balance and CG around. We also had a preset that put you in it immediately and could make it recoverable or non-recoverable. Had to show 'em that even though they did all they could to rescue the jet, you have to know when it's time to part ways with it.

Check out what Obi Gums had to say about deep stalls in the Viper back in '04 here (second entry down).

In this case, what's this "CCIP"?

CCIP is an improvement program, under which both Block 40's and Block 50's are brought up to the same technical standard. Search the site, and you will find quite a few articles and discussion on it.
PACAF Vipers were upgraded in Korea, hence the milestone marker

Man that's a weird looking picture...I'd swear that was a photoshop job with a model, except it has the JHMCS sensor that distinguishes a Block 40 CCIP jet.

I Still think it looks like a model though....

Check the root of the vertical tail, it has no antennae. Also the vertical tail is also missing that small thing at the middle top. Also no serial number. It could be photochopped.

You can normally spot a PS job by the file properties. The shadow on the airplane from it's canopy is a different angle than the shadows of the people. The airplane is in sharp focus; uncanny the lens would have such super capabilities.
