I am imagining the horrible graphics of Red Baron 3d (1998) played at a ludicrously crisp frame rate through VR goggles. The game had fast forward and play buttons because it took so long to fly over to the trenches or to ascend to a decent altitude. Solid idea though, it would be hectic with numerous biplanes dog fighting over France.

Edit: there are youtube videos of players using VR headsets and flying biplanes on IL-2 Sturmovik: Flying Circus (2019).
