Honorary commanders get behind-the-scene look into 412th Maintenance Group
                Honorary commanders watch a test run of a jet engine. Engines are run in the test cell facility to determine if there is a problem before and after maintenance is conducted to ensure all problems have been corrected before being reinstalled on an airplane.
