I'll second that! I've got a bunch of old Flying magazines from the 40', 50' 60's. The performance figures stated in the various manufacturers ads are rediculous. Some of their cruise numbers so far fetched that I can't imagine how they could explain the real numbers customers found after purchase. Every manufacturer was guilty.
