The two pilots killed in a helicopter crash while fighting the Dome Fire in Yosemite National Park have been identified by the helicopter’s owner, and the Federal Aviation Administration has released preliminary details on the crash.

The Precision aerospace company identified the men as Greg King and Ryan Cutter in a post on their social media account late Monday night. The company did not release further details on King or Cutter but acknowledged the public’s thoughts and prayers.

“These two men deserve every single one of them, as do their families and friends,” a company representative said in the post. “These two men brought honor to the mission. Their dedication and service will never be forgotten.”

The FAA’s initial incident notification said the helicopter, a Eurocopter AS32 Super Puma, crashed under unknown circumstances while on water bucket drops at the fire. The administration listed one flight crew member and one passenger on the helicopter.

The Dome Fire has burned 3,324 acres and is 15% contained as of Tuesday morning, according to fire crews at the scene. The fire continued to spread into the 2017 Empire Fire footprint, whiile a spot fire to the east grows. Officials expect spotting to continue as the fire moves north into heavy dead and down fuels.

“Fire behavior will remain moderate, with spotting behavior being a big challenge in the full suppression efforts of this fire,” officials said in the Monday morning update. “We continue to stage structure firefighters at Yosemite West and Wawona, supporting local communities and continuing prep work and contingencies.”
