Helicopter development began at Bell Aircraft in 1941 with the Bell Model 30 first flying in 1943. Bell Helicopter became the only part of Bell Aircraft still producing aircraft when Bell was purchased by the Textron Corporation. That part of Textron is now known today as Bell Helicopter. After a series of successful helicopter designs, the UH-1 Iroquois became the most famous helicopter of the War in Vietnam, and Bell Helicopter still designs and manufactures helicopters today.
