(KTLA) - Crews have worked non-stop for nearly a week straight in their battle with the deadly Eaton Fire, which was 33% contained at 14,117 acres as of Monday night. When the fire first broke out on the night of Jan. 7, thousands of people were forced to evacuate in a rush as the flames, some as tall as 100 feet, ripped through the Altadena region. Firefighters rapidly put up a heroic effort to save as many lives, homes and land as they could. Although thousands of homes have since been lost, one neighborhood is largely intact thanks to the efforts of a group of U.S. Forest Service firefighters based in the Angeles National Forest. That same U.S. Forest Service team on Monday provided an inside look at how they managed to save homes they were defending that first night near Kinclair Drive in Pasadena. In the footage provided by the crew, the intimidating blaze was both seen and heard – but it did not seem to phase the brave firefighters as they adamantly organized their attack. “Jonathan, careful, we can’t run out of water,” shouted a firefighter, giving orders to his crew over the loud raging of the massive flames merely feet away. “When we first arrived on scene, we were faced with walls of flames 50 to 100 feet, wind gusts in excess of 50 miles an hour,” said Robert Robledo, a U.S. Forest Service captain. “I’ve been fighting fire for 21 years and this is probably the worst I’ve ever seen the wind gusts, the ember casts and flame impingement on structures.” Members of this U.S. Forest Service wildfire unit were first on scene and worked tirelessly for the next 36 hours straight before taking a brief rest, and then attacking flames on another front on Mount Wilson. “We’re coming to a chaotic scene and we’re trying to bring calmness to everything,” team member Eduardo Cerna told KTLA's Chris Wolfe. “As we’re coming in, we’re noticing that a lot of people are rushing out.” As the firefight continues amid fears of strong winds rebuilding the crews are determined to keep moving forward. “Our main goal is to try to make sure public safety, life and property are good, and then that way we can safely do our job without having to worry about life, and then we can save as many homes as possible,” said Cerna. An electrical transmission tower in Eaton Canyon is under investigation as the possible cause of the deadly fire that bears its name.
