End of an era
A fitting end to the Shuttle Program as it was known.
Those old space birds completed some remarkable feats through the decades, sure the program wasn't with out its problems, but they were (and probably still are) way ahead in their day.
Rest assured tat in the next decade China will have an equivalent resuable space vehicle and this will get the U.S. Senate's asses into gear on designing and building a replacement.
We know that NASA are relying on the private aerospace sector to fill in the gaps, but I don't foresee any private organisation ever building something as groundbreaking as the Shuttles.
