Answer to Blue Sky TriviaQ. Why does the sky look darker when you look up from a cruising airplane? A. When flying in an airplane at 34,000 feet, you are above 75 percent of the atmosphere. If you look out and up, you’ll notice the sky is a much darker blue than you’re used to seeing. This is because you’re seeing some sky, but also some of outer space.
