WICHITA, Kan. (AP) — An era in Kansas aviation has come to a close with the departure of the last aircraft from a Boeing maintenance facility in Wichita, ending a 70-year relationship between the aircraft maker and the city. The Wichita Eagle reports that an EB-4 took off Thursday from Wichita bound for an Air Force base in Nebraska. Future work on the planes will be performed at a Boeing facility in San Antonio, Texas. Boeing had been in Wichita since 1927, employing as many as 40,000 workers at one time. Boeing sold its commercial business in 2004 to Onex Corporation, which formed Spirit AeroSystems. Boeing announced in 2012 that it would end defense work in Wichita. Former Boeing employees watched with sadness as the last jet left.
