I have just about given up. There is simply nothing on jetpacks, or rockets or whatever. I went to the library looked around, and found nothing. I asked the librarian if they might have something along the lines of what I needed and found nothing. I've looked online, looked at NASA's website. No one had anything! This of course frustrates me. I think I may need to stteer my research in a different direction. Perhaps I should contact some experts or something. It's worth a shot I suppose.
