She was 32, an only child, and was a senior manager for a company on the 83rd floor of the South Tower when the attacks began. Doi, along with some colleagues initially evacuated to well below the impact zone following the first plane hitting the North Tower. But just then, the tragic all clear announcement was made asking employees to go back to work. Doi took the elevator back up moments before Flight 175's wing crashed through her office. Excerpts from her emergency call are below, you've probably heard it before. In the recording you hear her mention hearing voices of people suddenly arriving; it's speculated that may have been Battalion Chief Orio Palmer, see below. Melissa Doi lived with her mother and was able to give the dispatcher her mother's contact information as well as a final message, "tell her that she was the best mother a person could have, and that I love her with all my heart and soul, and that I'll see her in the next world."
