How do you add pushback vehicles to aircraft?

If you want to add extra vehicles, people buildings etc I suggest downloading a program called RWY12 which is easily found on the web. This gives you the option of adding around 1000 new items to your airfield etc.Its very easy to use and its free!

The pushback trucks are actually built into the aircraft, so you’ll need to download an aircraft that includes one. Commercial Level Simulations have A300s, A310s and A340s, all of which have pushback trucks by default, although CLS aircraft are payware. If you’re after a free aircraft, download the Project Open Sky 737. I can’t remember if their 767 also includes a truck or not though. When you press Ctrl + P, the truck will just appear from nowhere!
