A small sea of fire retardant foam was unintentionally released in an aircraft hangar, temporarily covering a small portion of the flight line at Travis AFB, Calif., Sept. 24, 2013. The non-hazardous foam is similar to dish soap, which eventually dissolved into liquid, which was helped by high winds. 60th Air Mobility Wing fire fighters helped control the dispersion by using powerful fans and covering drains. No people or aircraft were harmed in the incident. (U.S. Air Force photo/Ken Wright/Released)
