One of the most haunting scenes in the film 3 Idiots begins in a quiet hostel room. A young engineering student, Joy Lobo, is passionately working on a small flying machine. However, his rigid principal, Viru Sahastrabuddhe, dismisses the idea when Joy updates him about his project. Threatened with disciplinary action for missing academic deadlines and crushed by the rejection, Joy throws his invention into the trash.
Later, his friend Rancho discovers the broken machine, repairs it, and manages to make it fly. The moment feels magical. Excited, Rancho flies it toward Joy’s room to surprise him, only to find him hanging from the ceiling fan.
For many viewers, this was their first encounter with the concept of a drone — a small flying machine capable of performing multiple tasks.
Years later, another Indian film presented drones in a very different light. In Uri: The Surgical Strike, the military uses a bird-like drone, known as an ornithopter, during a covert mission. The drone mimics the movement of a real bird as it flies across enemy territory, transmitting live footage back to a command centre. It allows soldiers to conduct discreet surveillance without putting human lives at risk.
These are not just cinematic moments. They reflect a real technological shift, one that shows how drones have gradually entered our everyday lives.
Drones as Most of Us Know Them
For many people, the first time seeing a drone in real life was at a wedding. A small buzzing machine equipped with a camera hover above the crowd, capturing aerial footage of the celebration and giving families a cinematic view of their special day.
Filmmakers, too, quickly embraced drones. They are now widely used to create breathtaking aerial and bird’s-eye-view shots of landscapes and cities — shots that once required expensive helicopter rentals and complex logistics.
Drones Beyond the Camera
While drones became popular among the public through weddings and films, their origins go back much further. From the early stages of their development during World War I, drones — formally known as unmanned aerial vehicles (UAVs) — were primarily used for military purposes. They helped reduce human casualties by carrying out observation, surveillance, and reconnaissance missions.
Over time, drone technology became smaller, smarter, and more affordable. Their role expanded far beyond flying cameras, finding applications in environmental monitoring, scientific research, and rescue operations. Tasks that once required hours of manual inspection or heavy expenditure can now be completed in minutes from the sky.
Drones in Agriculture
Farmers are increasingly using drones to monitor crop health, detect pest infestations, and spray fertilisers and pesticides with precision. This method reduces the excessive use of chemicals while improving crop yield and saving both time and labour.
Drones in Disaster and Rescue Operations
Equipped with thermal cameras and high-resolution sensors, drones can scan collapsed buildings, flooded villages, or dense forests to locate survivors. They are also used to assist in fighting forest and building fires. In situations where every minute matters, drones help rescue teams assess damage quickly and reach areas that are too dangerous for humans to enter.
Drones in Emergency Deliveries
In remote regions with poor road infrastructure, drones are now being used to deliver blood, vaccines, and emergency medicines. By cutting down travel time, they help save lives during critical situations where delays can be fatal.
Environmental and Climate Monitoring
Drones are also transforming environmental research. They are used to track animal movements, detect illegal poaching, and conduct aerial mapping of forests and coastal ecosystems. Scientists can now observe deforestation, monitor coral reefs, and study fragile habitats without disturbing them, leading to more accurate and less intrusive data collection.
Infrastructure Inspection and Maintenance
Inspecting power lines, wind turbines, bridges, and pipelines used to involve shutting down operations or sending workers into risky environments. Drones equipped with cameras and sensors now make these inspections quicker, safer, and far more cost-effective.
Drones in Entertainment
In recent years, massive drone light shows have begun replacing traditional fireworks in public celebrations. Thousands of synchronised drones can create intricate three-dimensional patterns in the sky, offering a visually stunning and more environmentally friendly alternative to fireworks.
Looking Ahead
What began as a military tool and later captured public imagination through cinema has now become an integral part of multiple industries. From weddings and filmmaking to agriculture, rescue missions, and environmental protection, drones are steadily reshaping how humans observe, document, and interact with the world around them.
And as technology continues to evolve, the role of drones in our lives is only expected to grow — bringing with it possibilities that once existed only in science fiction.
