"Planes 3" was ultimately canceled due to a combination of factors, including underwhelming box office performance of its predecessor "Planes: Fire & Rescue" and a shift in Disney's focus. Disney decided to prioritize its resources towards other projects, particularly within the main "Cars" franchise and new original content. Additionally, the animation landscape was evolving, and Disney sought to invest in more high-profile animated films, leading to the abandonment of the "Planes" sequel.
