Providing reference is good and should be encouraged in discussions, but I've already said that particular discussion needs to stop right there right then. Any further posts on that topic would have been deleted, regardless of who posted them or how valid they are. Look on the bright side, Lion is on a vacation and you are still here.
OK fair enough. I can respect and appreciate that.
But second question still stands besides the engine discussion. Heat shields. Why are they not there?!?! I'm sure the designers know the importance of reducing IR signature. Unless I'm oblivious to something that is obvious or maybe it was discussed on this thread that I missed or something. Heat shield thing has always bugged me.
