A stockpile of drop fuel tanks - one being carried by two members of ground crew of the 56th Fighter Group. The light-grey pile in the foreground were made of sheet steel. The silver-finished tanks in the background were made from a paper and plastic composition. The fitting of drop tanks to the underside of a P-47 Thunderbolt's fuselage provided sufficient fuel for longer range bomber escort duties.
