WASHINGTON (UNITED STATES) - The US capital Washington saw its worst air quality of the year over the July 4th weekend, as smoke from a massive fireworks display sent pollution soaring to levels considered very unhealthy for the entire public, data showed Monday.
Pyrotecnico, the company hired by the Trump administration's Freedom 250 organization, had set a goal of breaking a world record by launching 850,000 fireworks, with experts warning in advance that setting off such a great number over the course of just 40 minutes could be a recipe for disaster.
