In the early to mid 1960s, the French space agency had been thinking OTL of either southern France or French Guiana (or perhaps some other equatorial location) in which to place the spaceport. In the event that the territory of French Guiana is part of another country (e.g. Brazil), would the French have still thought of putting their spaceport in an equatorial location (e.g. Guyana - similar geography to French Guiana)? Or would they have placed it in the south of France (like in the Roussillon region)?
