"Each firefighter carried close to 100 pounds of equipment that day, but Jonas, a stickler for regulations, wasn’t about to let them drop any of it. Still, they moved down the stairs at a good pace. Matty Komorowski was last in line, and not worried. “We had a building around us. Everything was fine. It was clear as a bell.”

"The building was pancaking down from the top and, in the process, blasting air down the stairwell. The wind lifted Komorowski off his feet. “I was taking a staircase at a time,” he says, “It was a combination of me running and getting blown down.” Lim says Komorowski flew over him. Eight seconds later—that’s how long it took the building to come down—Komorowski landed three floors lower, in standing position, buried to his knees in pulverized Sheetrock and cement."

"Lim landed near Harris. “If Josephine doesn’t slow me down, I’m dead,” he’d later say. “I figured this out.” That captain who’d urged Lim to go ahead didn’t make it. “Josephine Harris saved my life,” he says definitively. Harris landed on her side, clinging to the boot of Billy Butler."
