If I were to spin you round and round in your seat for a minute (I'm

up and walk twenty feet in a straight line. Can you do it?

If I have an instrument that shows me how to walk straight, yes.

I call bull**** on this one. No you can't. Yes you do have an instrument
that shows you how to walk straight: your eyeballs (we won't do the
experiment in the dark at first) looking at, say, the road or the walls
around you or other fixed objects of your choice. An NO, emphatically,
you won't be able to walk straight, or even stand up. There are actually
neat and fun devices designed to do just that: spin you around and around
for a while (there was one at Beale AFB where I did the high altitude
training, I am sure you can find something similar elsewhere)

But in reality, aircraft do not spin round and round for minutes at a time
just because they are in clouds.

Not minutes at a time, but HOURS at a time depending on how long
the flight in the clouds lasts. Not quite spinning like the fun training
device I was mentioning, but the effect is just as good; better actually.
