Adobe Audition: Generating Tones and Noises

Today we were taught how to create our own sounds within Adobe Audition by generating tones or noises then altering them. I really enjoyed doing this, but I think I got better results using tones instead of noises. The first set of tones I imagined to be space ships or some sort of sci-fi vehicle passing, the second tone I thought sounded similar to a space ship engine starting up then the sound I made using a noise was meant to sound like a storm.
