When will commercially viable electric vehicles take to the skies?

A key challenge in building electric aircraft involves how much energy can be stored in a given amount of weight of the on-board energy source

As electric cars and trucks appear increasingly on U.S. highways, it raises the question: When will commercially viable electric vehicles take to the skies? There are a number of ambitious efforts to build electric-powered airplanes, including regional jets and planes that can cover longer distances.
