Beyond Visual Range, sounds cool. My professional work involves quite some Occulus and google cardboard. but it can give one super serious headaches and disorientation to the tune of falling back over/blacking out esp when plane is rolling etc. And one would also need two cameras on the plane for real 3d render, effectively halving the bandwidth.

I don't know of an out of the box app but If you can extract and render a frame of video, sync L-R and display using the cardboard api, you're done. Also checkout
