China covered up a lot more crashes then Russia ever could, especially concerning your J-10, there have been only 3 crashes of Su-30 , and of the three crashes only one pilot has died. 
PAK-FA/T-50 flameout embarrasses Sukhoi
Russia's MAKS 2011 air show closed with an embarrassment for Sukhoi, when the pilot of its second prototype PAK-FA/T-50 was forced to abort a take-off run after two bursts of flame erupted from the fifth-generation fighter's starboard engine.
The incident happened in front of about 200,000 visitors, who had gathered at Ramenskoye air base near Moscow on 21 August to watch a flying display.
Also referred to as T-50-2, or Side 52, the aircraft was forced to stop from a speed of around 100km/h, with Sukhoi test pilot Sergei Bogdan using wheel brakes and also deploying a brake parachute.
It stopped well short of the aerodrome fence, thanks to the 5,000m (16,400ft) length of the runway.
Sukhoi said the aircraft had suffered a technical malfunction but no damage, and that its pilot had acted "in accordance with manuals".
The company later attributed the issue to a "malfunctioning fuel supply system" and to the NPO Saturn Item 117 engine's full-authority digital engine control system.
To further Sukhoi's embarrassment, immediately after the incident the show's organisers promised the public that the first PAK-FA prototype would fly instead. This failed to happen, with the aircraft believed to have been sent for maintenance shortly after performing in front of Russian prime minister Vladimir Putin on 17 August.

Your above comment is typical of someone who is avoiding the topic--I asked for a source--where is it? I have given you examples that debunk your 'cover up' conspiracy but what have you provided? As I mentioned there has been an SU-33 that fell off the carrier deck due to the arresting cable snapping--there was no cover up, the Navy made it public. Moreover, there was a Mig-29 that crashed in an open field, the Air Force made the news public.
Read the sources posted, the sources stated that in 1998 the US Air Force planed to equip the F-22 with the K-36D ejection seat but for whatever reason likely politics, it never happened.
No I don't know.
So where is the source? If you make claims especially provocative ones about cover-up's you better back those claims with sources.
An interesting story, I completed a three month course in deception and spotting liars by someone with 30 years in a certain government/intelligence agency, your word choices and avoidance is a clear indication that you just through together a lie. Did you think that know one was going to challenge your claim? You dug yourself into a hole and it's been getting deeper and deeper.

WRONG.
LOL, you should do some research before posting such stupid claims. If you had you would know that the 5G Engine program is ahead of schedule. The first PAK-FA's will be equipped with the current engine and the new engine with the Flat Nozzles will come when they are ready. What "Examination day"? The glitch has happened before on numerous aircraft, F-111, Super Hornet, even the F-22 i think. There's nothing wrong with the engine, it was a sensor malfunction, which has now been replaced.
