Who do i contact to get overflight permission for Germany and Switzerland?

I am having trouble at work. My managing director has a Military Gazelle HT MK2 helicopter but only has a permit to fly in the uk. I need overflight permission for Germany and Switzerland and the CAA told me to contact the authories for both countries. I have scoured the internet to no avail as to go about doing this and all the numbers I rung keep passing me from pillar to post. Any help would be appreciated as this is getting desperate now and i really need to get this done!|||when you file your flight plan the permissions are arranged automatically|||Call the airport - the landing tower has to give permission to fly in the area so they should be able to tell you.|||Sounds like you have no idea what you are talking about!





You state you need to find out permission to fly over Germany and Switzerland!! well to get that far you will also need to file for permission to fly over the following:


Holland, Belgium, and France depending upon your destination





The British Civil Aviation Authority would supply relevant contact details of their counterparts on the continent ( all of which the pilot of the helicopter should know, he will also have to be able to file the relevant proposed flight plans and schedule for refuelling,)





You will also have to land for a customs and immigration check as well.





Your question does not rate a reply in the military section because of your claim its a Military Gazelle HT MK2 either.
