Swiss signs the Schengen treaty
Just heard on the news that Swiss signed the Schengen treaty yesterday evening. However, Swiss is still not part of the European Union so although the border controls have been formally abolished, there's no free flow of goods: you still have to formally import and export your things with the help of customs.
Anybody knows the practical consequences of this for GA? Will we still be required to fly to/from a customs airport when we enter/leave Swiss airspace?
