This is the beginning of a larger project that will eventually enable VR users to issue all commands from within a VR HMD without needing to use the keyboard. Right now there are just 20 basic commands for people who have the free version to use, and expanded version is forthcoming.
Let me know if you find any bugs. I have not yet tested the refuel option, but it should work. Please look at the README for known potential issues and bugs. For example the game does not seem to stop pushing you back when you request a pushback. When I tried it just did it forever, so I added another command called "Stop" to tell them to stop.
Edit: Uploaded v1.1 - Should help with some timing issues. The game favors longer timings but if its too long, then the game registers multiple keystrokes. Currently set at 0.025
