Ummm...

I know.

I've been in the aerospace business, on the technology side, for over two decades.

I've seen the Chinese in action first hand during that period.

I've met with hundreds of their scientists, engineers, managers, handlers, and spies.

Because I use my real name on everything I post, that's all I'll say except that while the opinion that I have formed about the danger that is China is personal, my professional life has given me insight(s) that the average person most certainly has not been privy to.

ps. I went through the C919 mock-up at last year's Paris Airshow.
