Small, Hybrid Aircraft

I honestly can’t think of a single thing that makes this at all credible. Air travel has to be safe, and closely monitored by government agencies. Even if the cost of fuel can be reduced, as is the claim, this will have very little effect on the overall cost per passenger.
This is akin to the piece I published about a month ago on the company that is developing personalized single person aircraft that it claims will replace automobile commuting to and from work. In other words, the skies will soon be filled with tens of millions of little airplanes piloted by people with 30-minutes’ virtual reality training and no pilot’s license. If that seems feasible, I’m not sure what to tell you.
