No it couldn't. The J in J-20 tells you this already.
Simply amazing !!! :O
What are the chances that it's a "F"-117 style intentional misdirection? I think the canards make that less likely too though.
So what we're actually seeing is a J-20 with camouflage patterns? That's what it looks like in the 2nd picture. And someone with engine knowledge should definitely shed light on the blue flame. Although russian engines are known for it, the Chinese could have gone down a similar path when designing the WS-1x...though yeah, we need someone knowledgeable
I thought exhause colours are dependent on the temperature, so reddish flame for lower temp, and bluish for higher, since aviation fuels are the same.
