Unmanned Aerial Vehicles

Description 1:

Unmanned Aerial Vehicles (UAVs), also known as drones, are mechanical objects that fly without a human on board. They are usually operated by humans in remote locations but are sometimes controlled by autonomous machines onboard the aircraft. UAVs range in size and shape and serve a variety of functions. Though originally developed for military use, UAVs are now used widely for commercial and recreational purposes.

Revised description:

Unmanned Aerial Vehicles (UAVs), which are more commonly referred to as drones, are technologically advanced devices that do not require the presence of a person onboard in order to fly. Drones are ordinarily operated at a distance by human controllers, but more advanced drones can be directed by autonomous machines onboard the aircraft. UAVs can be small enough to fit in the palm of your hand or large enough to resemble a human carrying plane. The architecture of drones also varies as the devices serve a variety of functions. Though the creation of drones was initially the result of innovation for national security purposes, the unmanned objects expanded their utility to include an array of commercial and recreational uses.

Description 2:

Once serving exclusively militaristic purposes, Unmanned Aerial Vehicles (UAVs) are now prevalent across society. They are called by a less technical name, drones, and are used by corporations and children alike. Unlike a regular aircraft, a drone does not need a human on board to operate. Instead, the control of the aircraft can take place on the opposite side of the globe. When advanced drones are equipped with autonomous machines that make real-time decisions about the path of the aircraft, human control is no longer necessary at all. Because drones serve a variety of functions, they can be big or small, modern or classic looking, and are built with amenities specific to their uses.
