"There was talk about doing the vomit comet," the actor tells TV Guide Online. "But I don't go on planes that are nicknamed 'the vomit comet.' I don't do things like that. I don't like the left lane on the freeway, I don't like vomiting on myself. It's a little peeve I have."

On the other hand, O'Connell says he loved every minute he spent in his space suit. "To throw on a NASA-made space suit with an American flag on the arm — it doesn't get any better than that. That's every little boy's dream come true."

O'Connell was so comfortable in his suit, in fact, that he occasionally nodded off while wearing it — which isn't all that surprising given that he had to hang from wires for eight hours at a time in the thing.

"I was out cold half the time. I had climate control in the suit," he adds. "It was a very comforting, womb-like experience."
