It's very nice indeed. I like these exploration type of add-ons, "going" to places you probably never see. One minor issue is some pop-in at the base airfield on a few objects, hopefully this will be fixed.
Possibly because that's literally the meaning of the word "schedule" according to most dictionaries? (e.g. in the Cambridge Dictionary: "a list of planned activities or things to be done showing the times or dates when they are intended to happen or be done")
I guess we're talking about a schedule in the context of project management software then, which would probably work with arbitrary "currencies" (like person-hours), idk, I haven't used that kind of software in decades... in this context, I'm just a "resource".
But then, what does being "fully on schedule" (quoting Mathijs) actually mean? If a project timeline is set up without dates, the only meaning I can think of is "a project is executed in a way that no resource is idle because it has to wait for dependencies". Which, in itself, is a feat.
