     Have you ever had a panic attack in mid-flight? Those that have will tell you it's not fun. And there are plenty of reasons that make people panic. Some of them focus on the state of the pilot. Are I hey tired? Stressed? Paying enough attention?

     Would these people feel any better if we could get rid of pilots altogether?

    The technology already seems to be there-drones are not a new invention. Armies use drones in war zones , where they are controlled remotely. Even helicopters can be pi lot less, and delivers aid supplies  to dangerous locations.

     Aircraft accidents are rare today, But when they happen* they are getting harder and harder to solve‘That’s why investigations often focus on “human factors”， identifying psychological and physiological issues as a probable cause.

     At the Consumer Electronics Show in Las Vegas in January. Chinese company Ehang displayed the first-ever passenger drone. To fly, the passenger needs to set up a flight plan, click “take off” and “land on a tablet, and the computer does the rest. There are other similar efforts to develop personal air transport systems in the US

and the UK. But be it a plane that’s controlled remotely# or by an artificial intelligence system. whether it's just a passenger pressing a button* or a ground crew pulling the wireless strings, one fundamental question hasn’t been answered yet: Would we feel at ease flying it we can’t see two smartly dressed pilots inside, calmly providing us with weather updates during a storm?

     It appears that people are more comfortable with a pilot directly at the controls, and on the plane. People are of the opinion that being in the vehicle while controlling it is easier than controlling it remotely.

    There is also one worry: the risk of the unmanned plane getting hacked (黑客攻击）. It would be necessary to have not only preventive but also recovery measure—to stop an attack from happening and “rescue” the aircraft during a hack.

    Today, it might be difficult for people to accept unmanned planes because when a plane stops, it falls out of the sky. And of course, many people are already nervous about flying, while not many of us are nervous about riding in a car or on a train.
