Construction work starts off base for taxiway extension
RAF MILDENHALL, England – John Broad and Paul Watson, contractors, fix a concrete post into a trench July 26, 2012, at RAF Mildenhall. The posts are lifted with a mini-digger, enabling the contractors to put fresh, semi-dry concrete underneath, before being lifted again onto the concrete. Broad then looks through the holes in the post, using them as a guide to make sure other posts are positioned correctly. (U.S. Air Force photo/Karen Abeyasekere)
