I searched for a song that told the story of the heroes of 9/11 Flight United 93 who brought down the hijacked plane thought to be headed for the White House or Capitol building. Not finding one, I thought I'd better write it. I borrowed the structure and melody from Woody Guthrie's heroic ballad of 1942, "Sinking of the Reuben James" which itself was borrowed from the Carter Family's "Wildwood Flower."
