Authorities in the seaside resort city of Anapa, Russia used a rescue drone to save a swimmer from drowning.
The rescued man swam out too far to the sea, could not return, and started drowning. The authorities of the city deployed a rescue drone that dropped a life preserver to the swimmer allowing him to remain afloat until emergency responders could arrive.
The use of drones for water emergencies has become more popular in recent years. For example, this year Californian police started testing the use of drones as lifeguards and Australian lifeguards now routinely use drones.
The involvement of drones in rescue missions can make operations significantly faster and enable lifeguards to save more lives.
