A team of 55th Maintenance Squadron Airmen tow an aircraft into the North Hangar at Lincoln Airport as part of a proof of concept exercise Oct. 23, 2020 as the 55th Wing prepares to operate out of Lincoln Airport starting early next year. The training not only allowed to test the hangars to ensure the aircraft would fit as expected and to identify limiting factors while there’s still time to fix them before commencing operations, but it also provided an opportunity to certify some personnel in things like towing aircraft into these hangars. North Hangar was originally built in the 1950s and was home to the Strategic Air Command's Lincoln Air Force Base. (U.S. Air Force photo by Tech. Sgt. William A. O'Brien)
