Tried the map today; the airfields show up in FMB, but there does not seem to be anyground beneath them at all- the airfields seem to be laid directly on water. Tried to create a quick test mission, but this would not load, made no difference whether air start or ground/water start. Cause may well be lack of solid ground under airfields. Will have to look further into this...........

Its probably been made by converting an existing map, but the old airfield positions have not been deleted.

Remember to make missions that map must have a few objects on it and a couple of bridges.
Don't ask why. I don't know, but it will fail to load without these.

Best way, if the map is not populated properly with objects is to delete the contents of actors.static and load the map into FMB Map Editor. Add a few objects and bridges. then load in FMB Mission Builder and make a mission. It should then work with an air start even if there are no airfields.
