While you're right, I'd be more sceptical due to politics. The people around Lake Zürich are up in arms over wind turbines. Even solar panels on mountain sides are too much (though that's hopefully less about noise.) I can't imagine the uproar if someone wanted to fire rocket engines regularly there.
