Hello, I'm Materialscientist. I noticed that you made a change to an article, MV Bretagne, 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. Materialscientist (talk) 22:54, 18 January 2023 (UTC)

Reliable sources
Take a look at WP:RS, then WP:SPS and WP:UGC. planespotters.net is definitely not a reliable source. Any questions feel free to ask. 10mmsocket (talk) 16:46, 28 January 2023 (UTC)

Please do not add or change content, as you did at Boeing 757, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. -Fnlayson (talk) 23:24, 14 February 2023 (UTC)

Please stop. If you continue to add unsourced or poorly sourced content, as you did at Aeroflot fleet, you may be blocked from editing. Jetstreamer $Talk$ 11:57, 10 February 2024 (UTC)
