These UAV are not toys, and have a high potential to cause grave injuries.

However, even when not directly overflying people, responsible UAV operators take a number of safety precautions to ensure maximum operational safety of the devices. For example, using an octocopter instead of a quad would allow a motor and/or a propeller (and sometimes even two) to fail in flight without losing control. Another example are GPS-assisted autopilots, that can monitor and enforce safe flight envelope (distance, altitude) and return the aircraft to its starting location in case of radio signal loss or low battery charge.
