US Airmen from the 439th Maintenance Squadron at Westover ARB, Massachusetts, prepare to check the fit of a C-5 Galaxy into Westover's Regional Isochronal Dock on 22 May 2013, to test the newly-constructed mobile tail enclosure, or MTE. Crews broke ground on 1 April 2012, for the MTE, which is a moveable structure on rails that will protect maintenance troops from harsh New England weather. The Westover MTE is the largest structure of its kind in the Air Force.
