Airplane food has a bad reputation, but the food itself isn’t entirely to blame—the real fault lies with the plane. A 2015 Cornell University study, found that the environment inside an airplane actually alters the way food and drink tastes—sweet items tasted less sweet, while salty flavors were heightened. The dry recycled air inside the plane cabin doesn’t help either as low humidity can further dull taste and smell making everything in a plane seem bland. According to a 2010 study from the Insitute in Germany, it’s about 30 percent more difficult to detect sweet and salty tastes when you’re up in the air. An interesting fact is that airplane pilots never eat what the passengers do. Even if there are two of them, they are served different dishes. this is important because in the event of food poisoning among the passengers or one of the pilots, there will always be someone left to handle the plane. https://www.travelandleisure.com/airlines-airports/airplane-facts?slide=08423e
