Or if "I knew", maybe I spoke to throw people off.

Seriously though, no offense taken, Eagl. I'll state upfront that I have no specific knowledge of either the F-35 or the F-15SE programs (I believe I said as much in my earlier post). If I did, I certainly wouldn't post even FOUO info, let alone anything classified. Everything I talk about above comes from unclassified references, or is educated conjecture on my part; the broadest terms, if I may borrow a phrase. They are basic concepts, and are all well understood (the devil, as they say, is in the details after all). Call me a "serious student" of the subject, is all. Heck, I read Jane's for fun!
