Go For Launch!, Air and Space
"In this unique time-lapse video created from thousands of individual frames, photographers Scott Andrews, Stan Jirman and Philip Scott Andrews condense six weeks of painstaking work into three minutes, 52 seconds. The action starts in the hangar-like Orbiter Processing Facility at NASA's Kennedy Space Center, where Discovery has been outfitted for its STS-131 mission."


This is an awesome video. Very well made.
I wish someone could write a few paragraphs answering the questions that have popped up, and even explaining a few things that most people don't notice.
