The launch of an American satellite on a Chinese rocket from Xichang China killed up to 500 civilians. Since Xichang is a mountainous region, no sea turtles were likely killed but disputed number of people were. The case was fully described in a Discovery Channel documentary and in greater detail at Airspacemag.com and in excruciating detail at thespacereview.com. We've included links to those sources below.

Aside from being a significant space launch disaster , this particular accident should be of particular interest to residents of Camden County.  Every space launch is by definition 'a test launch.' This is because each launch is the first time that exact assembly of components has ever been fired. Space-X suffered two failures in the past 12 months and Orbital Sciences had the massive Antares explosion on launch from Wallops Island, Virginia in October 2014. The Challenger exploded on the 25th Space Shuttle mission. Essentially, every launch is an experiment of at least some of its parts.

In the Xichang catastrophe, before the rocket had even cleared the support tower, it veered into a horizontal flight path near the ground and more than 30 degrees off course, traeling for 22 seconds before crashing into a residential area. 
Xichang was in a very remote part of China and the rocket crashed into the side of a mountain. The direct explosion did not kill the people, rather the shock wave collapsed buildings across the valley at 3am. Had an accident like Xichang happened from Spaceport Camden, Brunswick, Kings Bay Naval Base, St. Marys, and Fernandina were all within the same impact distance. The Xichang rocket should have been destroyed by flight controllers within a few seconds of launch when they knew something was wrong, but someone made a bad decision, or the self-destruct system did not work as expected, and the errant launch continued until the crash. 

Space launches are tricky and potentially dangerous things. They should be conducted where a civilian catastrophe cannot happen, even if the ‘impossible’ sequence of events happens.  And contrary to some expert opinions, however rare, they have happened. That  is why everywhere else in the US, vertical launch spaceports have been located directly adjacent to the ocean or on tens of thousands of unoccupied acres. That is also why launches are quickly directed away from the launch pad - so that a failure does its damage where less harm can occur. Those descriptions do not seem to apply to the Camden site.
