Hello, I'm Materialscientist. I wanted to let you know that one or more of your recent contributions to Aviation in World War I has been undone because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.
