Hey Sally, glad to see you presenting the great research you're doing. I am still thrilled to have been able to collaborate, as a Boeing researcher and Purdue AAE alum, with you on the project that Bill mentioned in his introduction. Your presentation focus on research that is very different than our collaboration project. Still very awesome stuff! Lab education is a very important part of a students training experience. It made a important impact on my own experience while I was there in the '80's. So glad you are focused on that as well. Stay with it. Glad you are able to put your family as 1st priority in off hours. That supersonic WT experiment was one of my favorites when I took the aero lab class with John Sullivan.
