Spending an afternoon with upcoming Petrolette Cass Moeller, I was so lucky to be able to gain an insight into what it takes to run a an aerobatics school... and what it's like to have a fly. Cass gave me warning that she was going to take me up when we scheduled our time together. Needless to say I was pretty excited... but full of questions worried about what my bodily functions would do when subjected to positive and negative G-forces...
