This is why we can't have nice quadcopters: "A tourist seeking to take pictures of Yellowstone National Park crashed a camera-equipped drone into its largest hot spring, possibly damaging the prized geothermal feature, a park official said on Wednesday."
It remains unclear whether the drone that crashed Grand Prismatic Spring last Saturday and sank into its hot bubbly depths ended up damaging the geothermal feature. Park officials are still trying to decide whether to remove it.
Drones are banned in national parks. The moron who crashed this one has not been prosecuted.
