Someone's going round beating the drum for a spaceport in Guysborough County. A concept just like it was floated a decade ago, with the rocket launch site in Cape Breton. The main selling point for Guysborough is that it's the back of beyond, so presumably few people on the ground would be inconvenienced. However:
Nova Scotia is situated right under one of the busiest highways of air traffic on earth. On any given day hundreds of transatlantic flights fly through Nova Scotia's airspace.
To get a sense of the volume of traffic we're talking about, watch this video made by the National Air Traffic Services of the UK. It shows the tracks of the 2,524 North Atlantic flights that occurred on one single day in August 2013.
NASA imposes a 60-mile diameter aircraft exclusion zone around Cape Canaveral starting seven hours before there's a launch. Source. So any launch in Atlantic Canada would be sure to require rerouting hundreds of transatlantic flights.
Here's an interesting quote from the aftermath of the Cape Breton spaceport proposal:
"I think more important than the actual location of the launch site was, did the company understand the regulatory environment in which they would have to operate?" said Alan Lindenmoyer, manager of the commercial crew and cargo program at the Johnson Space Center in Houston. Source.
Which leads you wonder, has anyone from the Guysborough spaceport group, or from the provincial government, talked to the civil aviation authorities?
