Jack Grandcolas, who lost his pregnant wife on United Flight 93, looks out at the ocean near his home in Pebble Beach, Calif., Aug. 18, 2021. Twenty years later, Grandcolas still remembers waking up at 7:03 that morning. He looked at the clock, then out the window where an image in the sky caught his eye — a fleeting vision that looked like an angel ascending. He didn't know it yet, but that was the moment his life changed. (AP Photo/Haven Daley)
