Fire threats and environmental concerns have prompted some US cities to forego traditional Fourth of July fireworks in favor of spectacular drone light shows this year.
Salt Lake City, Utah, tried out the alternative way of celebrating Independence Day on Saturday with its first-ever drone show.
The city’s mayor, Erin Mendenhall, said in a news release the new format marked an effort to minimize the area’s “high fire danger” and to lessen air quality problems caused by pyrotechnics.
