Flying on an airplane can be an awesome experience, but there is so much more going on than we see when we travel at high altitudes. Your friendly flight attendant may be quick with a smile and a glass of water for you, but there are some things they just won’t tell you. Like, don’t drink that water unless it came out of a bottle! In fact, you’ll be surprised to learn that you may not even want to use that water for washing your hands with. We know that germs can gather on an airplane, but we’ll tell you where those nefarious germs are most likely to be hiding, and it might not be where you think. We’ll also explain why they dim the lights before takeoff, and what happens if you don’t put your oxygen mask on in time. The poor quality of airline food has been fun of enough, so we are here to somewhat defend it with some basic science. First class may seem like the ultimate luxury, but in the case of an actual emergency, it’s the worst place you can be. And although airlines want to make you feel safe, they neglect a lot of expensive safety measures that could make you drastically safer. Haven’t you ever wondered why the flight attendant’s seats and seat belts look different than yours? We’ll also let you in on some secrets about what the pilots are doing while they’re supposed to be flying the plane.
