SOUTHWEST ASIA -- Senior Airman Matthew Young, 386th Logistics Readiness Squadron, performs a Flash Test on a sample of jet fuel at an air base in Southwest Asia, Feb. 12. The test determines the lowest temperature at which vapors from a test portion combine with air to give a flammable mixture, also know as the flash point.
