This World Trade Center Video is the Most Inspiring Thing You'll See All Month

One World Trade Center at ground zero has grown to be a soaring tower 1,776 feet above Manhattan, backed by $3.8 billion in funding to rebuild the tragic site of the 2001 attack. The 72-story 4 World Trade Center is slated to open in two months, and a planned National September 11 Memorial Museum is expected to welcome its first visitors next year.

Watch this EarthCam video capture the progression of the tower's construction since October 2004 to present day. 

"This building is a strong, visible image of our resilience, coming back after this terrible tragedy," said a lead architect David Childs in a PBS documentary called "Ground Zero Supertower."
