BBC News - Sink or Swim? The global drowning crisis
Unknown depths: an inability to swim can make even the smallest ponds dangerous
Every year, nearly 400,000 people round the globe die by drowning, making it one of the world's most common causes of accidental death.

Now several projects - from playpens to drones - are attempting to tackle the problem.
Drones for drowning?
Drones are used for everything from shooting films to monitoring livestock, but now two Iranian engineers are attempting to use drones to rescue people in danger of drowning
With nearly 400 drowning off the Caspian coast of their country every year, the roboticist Amin Rigi and engineer Amir Tahiri decided to look at how they might alleviate the problem.
"We attempted to create a submersible robot, then a surface based robot, before we realized that a flying robot was the best approach." recalls Amin.
This drone could save your life
PARS, as their new robot is called, is designed to work by flying out to potential drowning victims and dropping life rings allowing people in the water to stay afloat until they can be rescued.
The current prototype model is remote controlled, and boasts a range of four kilometres, with the ability to rescue upto four people at once.
Search lights allow it to perform night rescues, and it can be launched from both the shore and from the decks of ships.
Their tests have shown that it can perform a rescue four times faster than a human lifeguard.
First generation robots will begin operations in Brazil, Italy and Mexico in April this year.
The current model costs $9,185 (€8,100) a unit but Amin hopes the next generation will be cheaper.
He also hopes future models will be able to perform rescues with less human input, eventually performing fully automated rescues.

it was on the ground and on alert (guess drones are on alert 24/7 though 
)
