A model rocket is a small rocket designed to reach low altitudes (e.g., 100–500 m (330–1,640 ft) for a 30 g (1.1 oz) model) and be recovered by a variety of means. According to the United States National Association of Rocketry (NAR) 's Safety Code, [ 1 ] model rockets are constructed out of lightweight and non metallic parts.
An appalling accident rate [5] led individuals such as G. Harry Stine and Vernon Estes to make model rocketry a safe and widespread hobby by developing and publishing the National Association of Rocketry Model Rocket Safety Code, and by commercially producing safe, professionally designed and manufactured model rocket motors. Model rocketry by ...
Estes Industries was founded by Vernon Estes in 1958; in 1961, the company moved to a 77-acre tract of land on the outskirts of Penrose, Colorado. [10] [1] In 1969, Vernon sold the company to the Damon Corporation of Needham, Massachusetts, a company which also purchased a number of other hobby companies including a smaller competitor of Estes, Centuri Engineering of Phoenix, Arizona.
