Honoring the Heroic Hounds of 9/11 - PawNation. THE GREATEST GUIDE DOG On 9/11, Roselle and her owner were on the 78th floor of World Trade Center Tower One when American Airlines Flight 11 crashed into the building. Remaining calm and composed, Roselle gracefully led her owner down 1,463 stairs and up Broadway, away from the WTC. Through dust and debris, she guided him to safety, finding an entrance to a subway station and saving her owner's life.
