Greg Lindahl (37568) writes "Last May, I really enjoyed reading an Ars Tecnica post “The secret laser-toting Soviet satellite that almost was” [down, see mirror at archive.org.] It turns out that most of the details were taken from an article titled Soviet Star Wars published in the Smithsonian Air & Space Magazine in 2010. Here are the details of the plagiarism, including some other space history articles with similar copying by the same author. Ars Technica's response? Unhistory! They've removed the posting, but haven't published a retraction or explanation."
