Drones were first developed for military use in 1917 and have since been used extensively for defense, tactical operations, and air strikes. While drones provide advantages like accessing difficult areas and capturing images from new perspectives, they also present disadvantages like navigation challenges and raising legal and ethical issues if operated in restricted areas. Drones are now commonly used to capture live events, survey dangerous locations, deliver small packages, and film high-quality aerial footage for movies and commercials.
