How about some wholesome news for once? Recently, botanists in Hawaii used a drone to find a flower they thought was extinct: Hibiscadelphus woodii.
During the expedition that led to the rediscovery of H. woodii, Wood and Nyberg had hiked hundreds of feet down the Kalalau Valley cliffs, but the difficult terrain prevented them from going any further.
It was then that Nyberg deployed the drone, flying it further down the cliffs, toward the sea, to take a closer look at a specific area of interest. Able to get within a meter or two of the sheer cliff face, he was able to confirm the continued existence of H. woodii.
