class=\"sh\">A tool shop in a shed<\/h3>\n<p>Henry Berliner, son of the gramophone inventor and helicopter pioneer Emile Berliner, founded the Engineering and Research Corporation in 1930 in a shed on 5th Street NW, Washington, to make tools for building metal aircraft and propellers. Through propeller work he met Fred Weick, a NACA engineer obsessed with making flying safe. In 1936 Weick left NACA to join ERCO, and in 1937 Berliner bought 50 acres beside College Park Airport in Riverdale, Maryland, for <span class=\"imp\">a large new factory and airstrip<\/span>.<\/p>\n<h3 class=\"sh\">The aeroplane that would not spin<\/h3>\n<p>Weick&rsquo;s design became the Ercoupe: a low-wing two-seater with tricycle gear, limited elevator travel and, in many examples, linked rudder and ailerons so it could be flown without pedals. It was <span class=\"imp\">the first aircraft certified by the CAA as characteristically incapable of spinning<\/span>. LIFE magazine called it nearly foolproof. The Ercoupe 415 went on sale in 1940, but only 112 were delivered before the war stopped civil production, and ERCO switched to gun turrets and other war work, earning an Army-Navy E award.<\/p>\n<h3 class=\"sh\">Boom, bust and simulators<\/h3>\n<p>Peace brought a frenzy: in 1946 alone ERCO built 4,311 Ercoupes, expecting a nation of newly trained pilots to buy them. The market collapsed late that year. In 1947 Berliner left aviation and sold the Ercoupe rights to Sanders Aviation; the design lived on with Forney, Alon and finally Mooney, with <span class=\"imp\">5,685 built in all<\/span>. ERCO turned to flight simulators in 1948 and became part of ACF Industries in November 1954.<\/p>\n<\/div>\n<div>\n<div class=\"pull\">A Washington tool shop that built the Ercoupe, the first
