Hobbyist drones aren't supposed to fly too far from the ground. In the United States, drones are permitted to go no higher than 400 feet, unless they have special exemptions from the FAA. In the European Union, flights are limited to 500 feet above the ground. No matter the continent, everyone can agree that 11,000 feet is way too high for a quadcopter. Which might be why, shortly after posting a video of his DJI Phantom 2 drone soaring more than 2 miles high on March 3rd, YouTube user Tollymaster removed the video from the internet.
