U.S. troops stationed at Osan Air Base became heroes when they saw a Korean family trapped in a burning building.

According to CNN, U.S. Air Force Master Sgt. Daniel Raimondo was on his way to dinner in Pyeongtaek, South Korea when he saw a smoke stack rising above nearby buildings. He rushed to the scene and found a mother four stories up holding her infant child out of the window. The second floor of the building was engulfed in billowing smoke.

Raimondo and other U.S. troops responding to the scene found blankets and stretched them out beneath the window.

“Please just throw the baby!” Raimondo called.

Though she was reluctant, the mother did drop her child onto the blanket net waiting below. She then did the same with her other two children, and lastly, herself.

“The smoke and the fire was just horrendous,” Raimondo said.

“You could barely even see her at that point.”

The woman fell more heavily than the children and hit the ground beneath the blanket, but someone had had the foresight to put cushions underneath it, he said.

“We carried her into a safe location into a salon,” he said. “I just kept yelling and talking to her, ‘You’re alive! You’re alive!'”

The entire rescue was captured on a harrowing video.
