These pictures of the STS-134 elements in the VAB (sans Orbiter) were the last stacking pictures I was able to take before starting my new job with the International Space Station (ISS).
Pictures 51-95 are not from this particular flow of Endeavour but rather previous flows over the last several years. Given we are nearing the end of the program, I decided to add additional views gathered previously - note that this was before I invested in the good camera equipment. Access to the vehicle like this was one of the reasons I chose to invest in better equipment.
Looking at these pictures, it should become obvious as to why this was the most complex machine ever built by human hands - and why the program was so labor intensive and costly.
However, given all that it accomplished over its 30-year history (including things never done before and most likely never to be done again), the Space Shuttle Program will always be one of NASA's greatest accomplishments and 'an American treasure'.
