It was my nav's first trip in a GR1/IDS; he was mainly an F3 man but for flying qualities trials it made little difference. He only said 2 things throughout: "Eleven Thousand" and, when we were half way through the pull out, "Yeeeee Haaaaaah!". I have flown several other rapid rolling trials with him and he was always very comfortable with being thrown around like that.
We drank lots of very fine red wine that night atop of one of Rome's seven hills.
