Talking about puking as you do, has anyone actually felt nauseous at the controls? The only time I ever did, and I've done plenty of aeros and all the other good pukeable stuff, was when I did a long 6 hourish glider flight at mostly highish altitude without O2, between 8 and 9 thousand feet and I was having to work fairly hard at staying there. I had the vomit rush, you know the dry retch (sorry if you're eating lunch) every minute or so for a good half hour towards the end. Never been able to figure that one out, as passenger jets have a cabin altitude of 8,000 or so and I've never felt nauseous in one of those.
