As much as I'd like to do it, I'd be one of those guys telling the story about barfing in the borrowed helmet. I have a very, very low tolerance for the influences of motion sickness. I had to quit autocrossing because I wanted to puke after a few laps, and when I would go under the Golden Gate in a boat I would usually be down in head so I could just get it over with.
I about 1990 Eileen and I flew in a Beaver from Seattle to Vancouver, during which the floatplane pilot was told to immediately climb from 2000 ft to 3500 ft to give airspace to some A7s flying out of Whidbey Is. Suffice it to say I had had some (OK a lot of) by then rather rare '75 Chateau St Michelle Cab the night before. But even under the rough conditions I didn't leave a mess in the cockpit. It's not only girls who have to work out the good vs. bad of "swallowing". When we landed the pilot did thank me for the act. '75 St. Michelle Cab doesn't really taste that good the second time you swallow it, but it would have looked pretty nasty spewed over the right seat instruments of a De Havilland...
