Nearly forgotten amid the Union victories of 1863 was the Union attempt to bring the war back to where it started: Charleston, South Carolina. The siege of Charleston became the site of numerous engineering innovations that presaged warfare of the next 60 years, as the North tried to take the city and fort that symbolized the birth of secession.
On August 12, 1977 the space shuttle Enterprise made its first free flight. That is, it was detached from its Boeing 747 "Shuttle Carrier Aircraft” and let fly. It is difficult to wrap my mind around the fact that this vehicle that once was, to me, the symbol of the future is now, itself, history. That is, perhaps, as ironic as the fact that the First Space Shuttle, Enterprise, never went to space.
