Great map! And extremly difficult to navigate without GPS and we all know, there was no GPS in those days. I didn't install the new trenches and now there seem to be no trenches at all. How can i rewrite the original trenches (Just in case i want to do that) after installation? I'd like to have a look at the new ones but before that i must know how to rewrite the old ones, one never knows ... Very nice airports, to mention that ;-)
