Jet fuel smells like itself: oil, chemicals, potential. In a glass, it resembles vodka, or sometimes a pale tequila. It is less heavy than water, cheaper by weight than milk, and harder to set alight with a flaming match than ethanol. Where kerosene is more refined than diesel, so jet fuel is more refined than kerosene. For chemists, it is a jumble of Cs and Hs, and the occasional sulfurous S; for mechanics, it is something to avoid splashing on your skin. For the aviation industry, it is a puzzle.
