Today I took someone up and was planning to fly from LOT up to 06C (schaumburg) to hit up pilot pete's for lunch in a 182RG. however, right after take off they started hyperventilating and pretty much had a panic attack. I asked them after getting out of the pattern if they were good to continue and they said yes, but pretty soon they also started feeling nauseous, so I turned around and landed. This was their first time in a small plane, and they had said that they had problems with motion sickness on airline flights. After landing they were embarrassed obviously and actually brought up maybe taking off again but I decided not to. Anyone ever have a friend do this? Any ways they over came the panic? Back on the ground they said that straight and level was fine, but pretty much any little bump, change in pitch or bank really bothered them. Any help?
