John Farley
You seem to know very little about the center of lift on some Russian designs.
172 Driver - there is a saying about it being better to keep your mouth shut and be thought a fool than to open it and confirm that you are. With that comment you haven't just given confirmation, you have shouted it loud and long and also shot yourself in both (or maybe more) of your left feet. You obviously have not the faintest idea of who John Farley actually is, or of the great respect in which he is held. I suggest a little research is in order followed by an apology.
His response to your idiotic comment is one of extreme restraint and modesty.
