thats quick Hagar!
i dont usually bother the creators of stuff, i find it's somehing stupid i've probably done but i'd like HMS ocean for the missions i'm doing for myself, i've done two that work properly now based around the Northwest of England, thanks to Cody Coyote (i'm not saying how many BUMMERS i've gone thro' to get to 2 ::) ) still having prob's with positioning at the end of the runways, proper bases are OK, the simple strip's are iffy i'm either to one side or a country mile away, got the runway positions in free flight as per your tute. get there in the end, as you say trial & error.
i'm working out an 'assembly sheet' so i can put everything in the right place in the mission , events, triggers, enemy aircraft, ships etc etc, before loading it up easier to spot mistakes that way( i'm in AWE of people who can do it all in their heads) if it was easy there'd be no FUN in it
