the scaling problem might be real, but it's not really a problem for harbour air, whose primary routes are ~50km from vancouver to victoria or ~80km from vancouver to whistler on nothing bigger than a twin otter.
The scaling problem is real. There's no electric plane in the world that can do that route with passengers right now (including this one). The scaling problem is probably surmountable for this particular use case, but it's far from trivial.
