Imagine, you are on a flying plane. Suddenly you hear, the plane you are boarded on has NO FUEL. What will be your first reaction? Think… Till then I tell you something about future planes. Most probably 30 years later, planes will use cryogenically frozen Liquid Natural Gas (LNG) to fly instead of using fuel. Hope so, as the fuel cost will be decreased a lot, the plane fair will be a lot less.
