While researching that post about Heathrow at the weekend, I thought it best to re-read what the treaty actually says on the subject of landing fees. Quite sensibly, it says that each country can decide its own landing fees, but may not charge foreign airlines more than domestic airlines (Art 15)...
... when I noticed this:
Article 8 - Pilotless aircraft
No aircraft capable of being flown without a pilot shall be flown without a pilot over the territory of a contracting State without special authorization by that State and in accordance with the terms of such authorization.
Each contracting State undertakes to insure that the flight of such aircraft without a pilot in regions open to civil aircraft shall be so controlled as to obviate danger to civil aircraft.
