One Small Slip...
The Daily Manab Zamin said US astronaut Neil Armstrong had shocked a news conference by saying he now knew it had been an "elaborate hoax".
Neither they nor the New Nation, which later picked up the story, realised the Onion was not a genuine news site.
Both have now apologised to their readers for not checking the story.
"We thought it was true so we printed it without checking," associate editor Hasanuzzuman Khan told the AFP news agency.
"We didn't know the Onion was not a real news site."
The Onion article claimed that Armstrong had been convinced by a website written by a part-time librarian;
"It only took a few hastily written paragraphs published by this passionate denier of mankind's so-called 'greatest technological achievement' for me to realize I had been living a lie, " said a visibly emotional Armstrong, addressing reporters at his home. "It has become painfully clear to me that on July 20, 1969, the Lunar Module under the control of my crew did not in fact travel 250,000 miles over eight days, touch down on the moon, and perform various experiments, ushering in a new era for humanity. Instead, the entire thing was filmed on a soundstage, most likely in New Mexico."
Obviously, this is a major embarrassment for the newspapers involved, and clearly shows how modern "journalism" is really just copy-paste-spin (witness The Daily Mail's recent "pregnant immigrant" slant on UK population data)
You've got to wonder, though - how much other net-sourced nonsense has made it to the headlines as "news"?
