Reminds me of guard duty right before dawn.
Wool is the only fiber that naturally resists flaming. Unlike many artificial fibers which melt and stick to the skin when on fire, wool usually smolders or chars instead of bursting into flame. Although wool will burn under intense fire, it normally self-extinguishes when the flame source is removed. For safety reasons, many airlines use wool or wool blends for the upholstry fabric on their seats. That's why wool is favored by the U.S. military.
