In a tragic incident, two helicopter pilots, employees of Helicopter Transport Services, contracted by the U.S. Forest Service, lost their lives when their Sikorsky Skycrane helicopter crashed while battling a wildfire in Utah's Fishlake National Forest on Friday morning. The crash sparked a new fire that merged with the existing blaze, which has now ravaged approximately 174 square miles (nearly 451 square kilometers). Initially, access to the crash site was impeded due to the raging fire, but on Saturday, crews were able to enter the area and confirm the fatalities. The National Transportation Safety Board will conduct an investigation once they can examine the wreckage, a process likely to take over a year to determine the cause. Meanwhile, numerous fires continue to rage across the Western United States, with one closing part of Mount Rainier National Park in Washington. In Oregon, another uncontrolled fire has scorched over 30 square miles (77.7 square kilometers), while firefighters work tirelessly to control larger fires near Spokane, Washington. Elsewhere, nearly 20,000 people were forced to evacuate ahead of a fast-moving wildfire in British Columbia. Amid these events, the tragic death of 47-year-old Jason Ensign, killed while operating a bulldozer for a timber company, was mourned by firefighters in Oregon.
