A passenger on a Singapore Airlines flight this week noticed a small, circular indentation below the image playing on the seatback in-flight entertainment system in front of him.

Could that be, he wondered, a cameraThe passenger did the only logical thing: He tweeted out a photo and asked the Twitterverse for opinions, setting off a chorus of complainers on Twitter.Singapore Airlines also responded to the tweets, saying that the camera was not used by the airline to capture pictures or video.

It then told media outlets in a statement that the embedded cameras &have been intended by the manufacturers for future developments.

These cameras are permanently disabled on our aircraft and cannot be activated on board.

We have no plans to enable or develop any features using the cameras.&
