I was thinking that this could go together with VATSIM or IVAO.
Before and after your flight online, you could have ground handlers load/unload, refuel, start-up etc to complete your online experience.
Just like VATSIM have ATC Controllers, they could have ground handlers
I know it would be hard work to get it started, and I know it will probably never happen, but it's just an idea.
What do you think - Good or bad idea?
