you have to talk with the security guard at the entry of the castle... don't remember which phrase you have to choose, i think it was smth like "i give you now commands soldiers".. strange and maybe irritating is that you won't hear/read the security guard talking about airfield (he only said ok i tell you what i know and the talking together sequence was then finished) and i didn't had it after we talked on the map, but as i called wilm the driver and used the car, mayer knew where the airfield was...
