A plug-in hyrbrid airplane?

In November of 2011, American commercial airlines consumed 48.3 million gallons of fuel—every day—and paid a total of $49.8 billion that month to do so. And with increasingly tight operating budgets, fuel efficiency has quickly become a primary concern for the airlines. Boeing thinks one possible solution is its new plug-in hybrid jet concept that burns 70 percent less gas per flight with the help of local power grid.
