Yeap I've also heard this and seems strange to 'plan' to fly into 30+ kts of H/W but you forget some drivers like to day dream by getting as close to FL's as they can. I'm sorry observer but your a peanut!!
Unless you have an uncontrollable twitch in your hands I find very very smooth (and cool) at 7am and even more during winter...
From my experience flying miners in north west queensland, vomit is not something they do as they are very freq. flyers. Maybe the over powering smell of after shave is upsetting their stomachs!
and having to hand fly IFR charter isn't there something about that in the regs???
cheers
