U.S. Air Force Airman 1st Class Jordan Collins, 7th Equipment Maintenance Squadron aircraft structural apprentice, checks the sizing of a metal part July 7, 2016, at Dyess Air Force Base, Texas. Airmen in the sheet metal shop learn many metal-working techniques, so they are equipped to fix any structural issue on the C-130J Super Hercules and the B-1B Lancer.
