Imagine you are sitting on a plane that is bound for the U.S.. You sit back in your chair, relax and unwrap a bologna sandwich that was given to you by the flight attendant. Finally  you relax, and bring the sandwich to your mouth.

But when you take a bite into the sandwich, something pricks you in your mouth. You immediately taste blood, and spit out none other than a sewing needle that was lodged in your food. Unfortunately this was a very real occurrence for Delta Air Lines passengers in 2012.
