Cape Canaveral's Launch Complex 14 is best known as the launch site for NASA's "Friendship 7," the flight that brought John Glenn fame as the first American to orbit the Earth in 1962. Now, more than 50 years later, the complex and other National Historic Landmarks are rapidly falling into decay. Challenged by limited funding for major preservation projects, the Air Force has turned to cutting-edge technology to document and preserve Cape Canaveral Air Force Station's historic launch structures, before it's too late.
