Re: "VR for working on a plane" - you could look into XR glasses like the ones from XReal or Viture.

I've been considering a pair for myself after hearing good feedback from some friends, and seeing some good reviews online.

The latest versions have head tracking so the virtual screen remains "pinned" in your view.

They're also much smaller and easier to carry compared to a full VR headset, and they can plug into almost any device (laptop, tablet, phone) and just show up as an external monitor.
