A tanker carrying liquefied natural gas (LNG) is a giant Thermos bottle longer than three football fields. LNG tankers carry nearly three billion cubic feet of natural gas that has been chilled to -260 degrees Fahrenheit, converting it to a liquid and reducing its volume six hundredfold. One tanker holds enough gas to heat about three million homes for four and a half days—or if the tanker were hit by a rocket, the spilled gas could vaporize and ignite in the air, causing second-degree burns and damaging buildings a mile away.
