No-pilot plane idea was around for a while. Apparently, self-flying planes would help to save $30 billion per year. But there are lots of topics to discuss before realizing it. The most important questions are: how safe is it? Who will deal with the emergencies? The medical help? How to protect from the hacks?
We believe, one day, will have the answers to those questions and we will be using self-flying planes but it will take tame. Remember when the self-driving cars where just in the movies? It took time but we have it now and we accept it as a normal thing.
