Battery powered anything, has a long way to go before it is really a viable mode of transportation. In real world use tesla cars have 40% of the range they claim, as proven by me in winter. In the summer holding it to the floor up a mountain pass put tesla into limp mode because it couldn't handle it. Their joke of a semi truck could not be more pathetic. So why would anyone expect an electric plane to be useful at all. I live a 3.5 hour drive away from Harbor Airs headquarters, and them just trying this lame stunt, has made them a laughing stalk in the area.
