Hello, I'm Graham Beards. I wanted to let you know that one or more of your recent contributions to Trinity (nuclear test) have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the help desk. Thanks. Graham Beards (talk) 17:15, 9 February 2020 (UTC)
