Chief Master Sgt. Wendell Addison, 89th Maintenance Group superintendent, observes five 89th MXG flying crew chiefs perform pre-flight checks on a C-32A at Travis Air Force Base, Calif., March 13, 2015. Addison often observes and assists Airmen first-hand as it allows him to make informed decisions and opens opportunities to draw upon his vast knowledge and experience to provide constructive inputs and improve the organization.
