Hello, I'm BilCat. I noticed that you added or changed content in an article, Mikoyan-Gurevich MiG-21, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. BilCat (talk) 11:05, 23 May 2023 (UTC)

Please do not add original research or novel syntheses of published material to articles as you apparently did to Sukhoi Su-7. Please cite a reliable source for all of your contributions. Thank you. BilCat (talk) 11:17, 23 May 2023 (UTC)
