excerpt from Drones
Unmanned aircrafts were originally designed for military use. They were initially used as target practice. However, as the technology
became more advanced, the military found different ways to use drones. Eventually, UAVs were sent into enemy territory to fly overhead
and survey the situation, which kept pilots out of danger.
After seeing the successful use of drones in the military, civilian organizations began to employ the use of UAVs. Police departments
now use drones to survey crowds during large events. Fire departments use drones to look for people in collapsed buildings. Drones
have been used by firefighters to survey and create containment plans while battling wildfires. Search and rescue organizations also
use UAVs to help rescue people who are lost in the wilderness or at sea.
Private companies use drones as well. Energy companies use the aircraft to survey power lines and oil pipelines. Because these
drones typically include cameras to relay pictures or video back to the operator, they save the company time and money. During a
recent oil spill, UAVs were used to assess the damage and to check how far the oil had spread.
The popularity of drones has grown steadily as the many uses for the aircraft have become clearer. For example, drones were used
during the 2014 Winter Olympics in Sochi to film skiing and snowboarding events. The drones allowed cameras to get close to the
athletes without the use of the bulky pulley systems normally used at sporting events. Filmmakers have also begun using drones to film
scenes in movies. The drones can capture images of large crowds and wide landscapes.
