Drone delivery itself isn't vaporware, and will almost certainly happen. However, the title referring to "the biggest drone superhighway" is the kind of BS the current UK government likes to put out. I am surprised it isn't sold as some kind of direct benefit of Brexit. If you read the article, it is about a small amount of funding to scale up trial drone delivery. As the article implies a lot more research and investment is needed to scale up drone deliveries to an industrial scale, beyond isolated success stories.
