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

Click here if you really want to see what the picture was. We don't recommend it.

The tweet was pulled down about an hour later, but it didn't stop it from spreading through Twitter very, very fast.

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

We apologize for an inappropriate image recently shared as a link in one of our responses. Weâ€™ve removed the tweet and are investigating.

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.
