Congratulations on surviving! Always good to know that a cool person has avoided dying for another year. Here's to hoping for many more!

Out curiosity, and unlikely to be something that the wind tunnel operators mentioned, but a question that reading your description made think is: is the relative wind speed in a wind tunnel like this higher, lower, or around the same as the wind relative wind speed of actually sky diving? I have no idea how to check, and no answer, but it's an interesting question I think.
