For some of those who haven't bought the new edition yet, I now have the Handbook of Model Rocketry, 7th Edition marked down to $17.47 and this is the new price, not a "sale" price. It retails for $22.95. Because of recent "developments", I can now compete more closely with some of the big book stores on the price. And check out the "The Complete Book of Spaceflight: From Apollo 1 to Zero Gravity" while you're there. It retails for $35.00 and I have it for $28.97.
