Can you use the jetways at the airports so that it is more realistic.
Some scenery downloads are more realistic. Pay-ware will do it.
If you max out your scenery slider (to the right) it will show jetways at most MAJOR airports.
You can move the aircraft (pushback) by using the "Shift+P" keys, it starts slowly at first so be patient.
You can stop it the same way.
I think "Bremen" scenery in our scenery forum post has moving vehicles.
😀 There are some more here ➡
