It all started during this pretty routine conversation with a customer:
@USAirways Unhappy that 1787 sat for an hour on tarmac in CLT because overweight, resulting in over hour late arrival in PDX...

@USAirways yeah, you seem so very sorry. So sorry, in fact, that you couldn't be bothered to address my other tweets.

Some people are saying @USAirways was hacked but it looks like an inside job.

• The photo was actually tweeted at the airline earlier today.
• The photo was also trending on Reddit's very NSFW shock imageboard Spacedicks last week.
• The graphic picture is originally from a German-language amateur porn and shock site.
UPDATE: US Airways has cleared up some of the confusion around how the image was posted.
According to a spokesperson for the company, US Airways was attempting to flag an inappropriate tweet that contained the graphic image. In doing so, the pic.twitter.com URL was copied, as well. Then the graphic image was inadvertently pasted into a tweet sent to another user. While the two tweets were live they actually linked to each other. The airline's spokesperson said they're very sorry for what happened and that it was an honest mistake.
