that's not quite correct. They're still in Danish territorial waters when they launch. The reason they launch at sea is safety. It's hard to know exactly where the rocket will land, and there just aren't any good places in Denmark where there's a 50 mile radius where you can be certain that nobody will be hit by debris. The part of the Baltic they launch from is actually a millitary training area that they borrow every year for launches. Disclaimer: I'm involved with Copenhagen Suborbitals.
