Will’s book of choice today, which he dug out of the storage room we call an office.

Omar Eduardo Rivera, a blind computer technician, was working on the 71st floor of the World Trade Center’s north tower on September 11, 2001, when a hijacked plane flew into the skyscraper. After Omar and his guide dog, Salty, fought their way to the stairwell, he unclipped the dog’s leash and ordered him to go. Convinced he would die, Omar wanted to give his beloved Labrador retriever a chance to survive. But Salty refused to leave his owner’s side, despite the panic and the intense heat. For nearly an hour, Salty patiently guided Omar down 70 flights of stairs to safety. The tower collapsed shortly after they escaped.
