Hello, I'm Fraggle81. I wanted to let you know that I undid one or more of your recent contributions to Aerodynamics because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Fraggle81 (talk) 03:31, 13 December 2012 (UTC)
