    Yes, but JAS-39 has other attributes the FC-1 does not: low observability (big thing), super cruise (I was very surprised to find out about this), multirole capable (from the onset of the design), and probably AESA soon.

    So you're saying F-16 block 5, 10, and 15, have no difference in performance than block 50/52?

    J-10 is a Lavi mod, with Russian help. That may not fit into your world view but it's a fact.

    The avionics in the pic belongs to F-15c. JF-17 is more advanced than that apparently.
    Glass cockpit makes the fighter 4th gen? How about the radar? Multirole capable? Even the fuselage design?

    Out of curiosity, what defines "a pretty amazing job" in a maiden flight? Not crashing is all I can come up with.

    Edit: This is a cool looking airplane.

    Another thought just came to me: is this the true 1st flight of this plane? All 1st flights are inherently dangerous. These are complex systems working together for the first time in their intended environment. We can do thousands of computer simulations but nothing beats the real thing. The PLAAF is surprisingly open about this flight. What if something went wrong and it crashed? That would be a major loss of face.

    Could it be that this plane had already tested elsewhere and was moved here to a populated area for a staged test?

    I'd say it's a near certainty.
    I enjoy being wrong too much to change my mind.

    It would also explain it's mature look i.e. coating

    That would make the flight, say in either early 2010 or late 2009, would it?

    Gripen has pseudo-supercruise; it can't supercruise with external mounted weapons due to drag.

    The 40 hours may be in reference to the WS-10B variant, which is built for TVC. Reports were going out a while ago about how the Chinese were unable to master the TVC technology because the TVC variant for the WS-10B would invariably fail before the hundredth hour.

    I think it's unreasonable to believe that the WS-10A has the same problem, because it's known that the WS-10B has significantly reduced MTBO / MTBM compared to the WS-10A, and if it did, it would be more than utterly unusable.

    Completing all tests and meeting all requirements?

    You perform all tests to see if it meets all requirements on maiden flight?

    No. But tests were conducted during this flight, and although China calls it the J-20's maiden flight, chances are they've already tested it before with a different engine. The sounds coming from the engine suggest that it is not Russian, and short sliding distance (around 200 meters according to spectators) +almost effortless lift-off indicate the engine has a lot of thrust power. Could this be the WS-15?

    J-10 cockpit doesn't look like that and J-20 wouldn't have its landing gears out at that altitude.

    You are wrong. I thought the same too until highsea showed me this document by SAAB that mentioned the JAS-39 achieved supersonic speeds with external stores on military thrust. The Swedish airfoce found out because the locals complained about the sonic booms over their town.

    JAS-39 is an amazing airplane.

    I was so shocked at this ability that I remembered where exactly I saw the reference.

    Also, given the size of this thing, anyone noticed how LONG the landing gears are?
    The second photo is also ps work, modified from a F-35 picture, so of course it looks like a F-35.
