With every new beginning comes hope. Rebuilding Twin Towers shows how we remain tough and resilient even in the face of adversity. They showed the world how our nation remains standing despite the challenges we face every day. It also shows how we remain united in our love for our country. Many of the local unions helped in rebuilding the World Trade Center into the Freedom Tower that you see today. And we commemorate this by writing their union numbers in the bird's feathers.
