Probably a stupid question, but why can't these lost pilots just maintain their attitude indicator in the middle, fly straight, grit their teeth, and wait to get out of the cloud?
Not at all stupid! Very real question that's been asked by aviation safety agencies around the world for decades! Sometimes there are genuine issues with instruments. As well, note that most GA airplanes operate their crucial instruments and gyros via vacuum pump and they need to be re-calibrated after a while even in regular flight. But I believe much more frequently, inexperienced humans distrust their instruments…
I was practicing increasingly denser fog/low visibility ILS landings of the F-16 in DCS, on my TrackIR'd 32"x3 triple screen sim rig (with transducers for buffeting sensations etc).
With triples (and much more so with VR, I'll transition to a Crystal "soon") you do develop a semi/meta(?)-"physical" connection with the sim after a while.
At a point visibility got so reduced I would completely experience vertigo. Even though I told myself it's only a sim, just look at the instruments (and the F-16 has so many, including HUD with the ILS glidescope), my head would spin out and I'd completely bork the landing.
Only after several more hours was I able to do it (with visibility so bad that the runway would only pop out when right on top of it metres from the ground). It would take a lot more to get comfortable with it, but by that point I had enough and - I still have nightmares about it. :)
Can completely understand how cloud based vertigo in a real plane with your life on the line has killed and will continue to kill so many. Mad respect to the real pilots here who have mastered this.
