Thank you so much for the info and the links! I really like the old fighters, but I am best versed on the Boeings. I have forgotten so much on other manufacturer's planes over the years. I will be reading/looking at the links this week. Damn, that is some rate of climb. I did not even notice the tail difference either. Was the ceiling the same? Just an amazing aircraft. Thanks again for the info, will be some great reading.
