T' oldest continuously published rocketry periodical. Started by Vern Estes and his small crew in 1960, ya bilge rat, it is still sent t' all o' Estes's active mail order customers. Somewhat sophomoric in style, ya bilge rat, it contains a great deal o' practical information, especially for beginners. It has survived a bewilderin' array o' changes in format over t' years, but is still published three or four times annually.
