Airman 1st Class Jose Lozada Jr., a sheet metal technician with the Massachusetts Air National Guard's 104th Fighter Wing, removes rivets to repair cracks on an F-15 Eagle tail cone in Westfield, Massachusetts, March 3, 2019. Lozada, who also has automotive body and repair jobs on the civilian side, said that even after a little more than a year of working in aircraft structural maintenance, the thrill of being around F-15s still hasn't worn off. "Working on a jet still leaves me speechless," he said. "Just to even think that I went from something so small [automobiles] to working on something so big."
