I made a simple but realistic VR Flight Simulator in WebGL and THREEJS for Oculus Go, but maybe works also with other devices such as Rift and Gear but not tested, inspired by this video: https://www.youtube.com/watch?v=ZKyOM7rMN-k , repository: https://github.com/shervin88/WebVRFlightSimOculusGO
this is the link of the Sim if you want to test it:

I hope someone could be interested to fork and improve it, thanks
