Never ever. =] Not even close. I have done acro, and soaring (at the same time. hehe)
me just mentioning the 60 degrees of bank going around a tight rough thermal for 10 minutes at a time, every few minuts on a 6 hour 300 mile glider race task. :nana2:
The only time I have ever felt a little queasy from motion sickness, would be when I had to (got too) ride "Superman" (really cool roller coaster in Chicago) 6 times in a row at 11PM. :buck:
Fun stuff.
Havent had any passengers blow in the plane, but two have had to pull over on thier way home. I hope that doesnt change next year when I am giving 15 glider rides a weekend. :whatever:
