Most stories involving drones usually end with the camera crashing or being taken out of the sky with a javelin. 

Which is why it is refreshing to see one about a daring rescue. YouTube user coolkidirish shared the video of the rescue and provided some detail as to why it was necessary. Apparently a guest somehow managed to get trapped in his bathroom.

"they were unable to get the door lock to open from the inside," he wrote. So he used his drone to hover outside the bathroom window so the guest could tie the key to a long piece of string dangling from the drone. 

"We successfully retrieved the key and opened it from the outside for her," continued coolkidirish. "Mission success!"

Now obviously there's no way to tell if there actually was somebody stuck in the bathroom but we'll give coolkidirish the benefit of the doubt.
