The greatest (and most intense) drone save videos

Drones are smart.

Not the military kind - they're terrifying. The "fly them in your garden, pester the neighbours and alarm the local authorities" kind of drone. (Incidentally, here are five of the best.)

In addition to their HD camera wielding abilities, the majority of modern drones and multi-bladed 'copters have a fail-safe procedure that kicks in when its battery begins to run dry.

Rather than falling out of the sky in an expensive blur of plastic and potential pain, drones will begin an elegant, unstoppable descent to the earth as soon as the battery reaches critical levels, ensuring it makes a soft landing. That is unless it's being flown over a body of water - a predicament that seems to be occurring with hilarious regularity.

Here are three wonderful examples of the kind of evasive action drone owners are forced to take should they be flying their drone over water with a near-empty battery. The fools.

And of course, this is what happens when the owner isn't able to save the day.
