Speaking of electric vehicles, the last I heard Harbor Air, Richmond BC, is planning to test fly an electric powered Beaver this month, and then continue along the path to certification and a first commercial flight by 2021. All that going well, they will then begin converting all their fleet of 40 planes to electric powered. The bulk of their business being short haul, harbor to harbor commuter traffic, it would seem to be the perfect operation to adopt the new technology.
