This paper describes the most critical aspects of security and the safety of drones, the interruption of privacy, benefits that the drone offers to human environments, as well as the challenges of drones in health and industries. A significant amount of research has stimulated this type of technology. In short, the drone is one of the newest technologies of the last century. It was used mainly for the military and was later shifted to be used in civilian markets for such purposes as news gathering, scientific research, toys, and entertainment. Drones are used directly by humans, so this drone is technology that has a direct impact on people. This impact may be for positive or may do some harm, creating a negative experience for the user or people. Positive effects of drones include support for businesses and improved lifestyle. For example, drones were used to eliminate Malaria in some developing countries; they also transport goods for medical/commercial purposes and are part of traffic management and mapping. Of course, nothing is perfect in life. The drone has many serious impacts on people's safety. This review fails to cover all drone aspects, particularly the vast potential for private military use.
