"Why was a plane able to fly over New York?"

Well, for starters it's published, and publically available. Secondly,
I've flown a lot around Paris and France in general. I admit I haven't
flown in Germany, but I do go to Munich several time a year and the
skies over that city are hardly buzzing with light aircraft (like zero)
so perhaps it's more restrictive than you make it sound?


Berlin has the only restricted area over a big city in Germany. It is
limited to the very center of the administration. So it is exactly as
non-restrictive as I make it sound.
