On of the problems when dealing with a socity like China

Keith, this ignorant civilian would like to know if it is possible for
the Chinese
to have a good understanding of what is needed to develop this
aircraft fully
as a result of stealing the information (i.e., hacking military
computers)?

Cheers . . . J.

They have some very good engineers who could come up with some real
innovations.

That said, if they depend on stolen information, it would be very easy
to plant deliberate misinformation in places they can hack (with some
effort). That is the flaw in stealind information.
