Hello, I'm Dr.Pinsky. I noticed that you made a change to an article, Timeline for the day of the September 11 attacks, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Dr.Pinsky (talk) 06:39, 18 August 2022 (UTC)
