US Airways may have single-handedly redefined the word "blunder" after posting a photo of a model plane being inserted in a woman's vagina on the company's official Twitter account.

The photo has been removed after lingering for about an hour on its timeline but that didn't stop social media users from screencapping and reposting it.

Both Buzzfeed and Deadspin have posted the NSFW image in its entirety on their sites. You can head there if you're interested in seeing the photo but be warned: graphic content lies ahead.

Based on the company's Twitter account, it seemed the airline was replying to two customers under the usernames @ElleRafter and @ThatKATZkat who were unhappy with its service.

@ElleRafter's conversation took on a similar format before the photo appeared.

US Airways apologized for the photo and said it is investigating how it made its way to the company's 419,000 Twitter followers.

The Huffington Post Canada has reached out to the airline for comment and will update the story once they reply.
