CNBC has published a video about the future of manned aircraft, the development of unmanned pilot technology, and the development of remote control systems.
In the details, the two American companies, "Reliapil Robotics" and "X Wing", both of which are in the state of California, are working to develop systems in aircraft that can fly by themselves without the need for a pilot.
Instead of making new aircraft, both companies have modified and developed a "Cessna Grand Caravans" plane, so that it can fly autonomously, and can be controlled and operated by a person remotely if necessary.
Both companies said that they are working with major logistical companies to supply them with autonomous aircraft, and this may be the "first use case" for these aircraft, if the US Federal Aviation Administration approves and authorizes their use.
