Being weightless is a sensation hard to fathom when you've been an Earthling all your life. In zero gravity, the inner ear, which controls balance, isn't quite in synch with what your eyes are telling you. Nausea is often the result. Could virtual reality dry-runs on the ground help? That was the question in our proposal, and it was a winner. We were invited to Johnson Space Center in Houston to ride the plane. I was probably more excited than any of my students. Floating! But late in the process, I got bad news. NASA made it very clear that under no circumstances could faculty advisors fly with their students. I was heartbroken, but I was not deterred. I would find a way around this brick wall. I decided to carefully read all the literature about the program, looking for loopholes. And I found one: NASA, always eager for good publicity, would allow a journalist from the students' hometown to come along for the ride. I called an official at NASA to ask for his fax number. "What are you going to fax us?" he asked. I explained: my resignation as the faculty advisor and my application as the journalist.
