Spirit AeroSystems executives Mike King and Buck Buchanan to retire

Two key Spirit AeroSystems executives plan to retire this summer.

Spirit executive vice president and chief operations officer Mike King and senior vice president of advanced projects Buck Buchanan have announced their plans to retire.

Both will remain with Spirit until their retirement dates, which are yet to be determined. Their successors have not been selected as well, said Spirit spokesman Ken Evans.

King and Buchanan both started working for Boeing Wichita in 1980, then joined Spirit after Boeing sold its Wichita commercial aircraft division in 2005, forming the stand-alone company.
