I get uncomfortable up high, don't know why.
That is the "high wing phenomena"...and one of the reason's I have a low wing aeroplane
....Me and a buddy were flying back into the LA basin from Nevada, it was one of those murkey days and we were at 12500. The mountain peaks could be seen ahead but other than that it was kind of milky everywhere (not mist, cloud or anything, just milky) and it was turbulent, bouncing us around . Looking down you could make out the desert below ok. I was sitting there thinking, blimey I feel like I have got vertigo....then my buddy (who if flying) says here, you fly I think I have got vertigo....! Don't get it with low wing aeroplanes.
