A German tourist who crashed his drone into a lake at Yellowstone National Park in July has been banned from the park for a year and ordered to pay a $1,600 fine, according to the Associated Press. The incident was separate from another drone crash that occurred at one park's most popular hot springs in August. Both incidents occurred after the US National Park Service moved to ban drones at all national parks beginning in June. High-profile consumer drone crashes have been occurring with increasing frequency in the past few years as the US Federal Aviation Administration struggles to meet a 2015 deadline to implement new policies to guide their use by private companies and individuals.
