A Jetpack is a device worn on the back that propels a person into the air using jet or rocket engines. It allows for vertical flight and can be used for various purposes, including entertainment, military applications, and search and rescue operations. Jetpacks typically use fuel or compressed gas to generate thrust, enabling short flights. The concept of a jetpack has been popularized in movies and television, often associated with futuristic technology. While several prototypes have been developed, practical and safe commercial use remains limited. Companies like JetPack Aviation and Gravity Industries are working to advance this technology for potential everyday use.
