    The Economics of Airline Class

    This is a Wendover Productions Video made possible by Squarespace–Make your next move with a beautiful website from Squarespace. This video is a bit of a continuation to my last one–Why Planes Don’t Fly Faster. I ended up talking a lot about the Concorde–the supersonic plane–but part of the story was left untold.

The real money, at least for the traditional airlines, is in premium cabins. Let’s take, for example, this British Airways 777. There are 224…

    Bird Digestion – Adaptations for Flight

    Bird flight is beautiful. But birds sacrifice a lot for their ability to fly. Like food. Because food is heavy, and it makes flying harder. A bird would not do well at an all-you-can-eat buffet. Like, they might have to walk out after eating instead of flying. So let’s look at the bird gut to see their compromises that enable flight. Starting at the beginning, in the mouth. Birds save a lot of weight by not having teeth. Obviously, they save a lot of weight by not having a mouth full of chompers, but it also saves the weight of strong jaw muscles that other animals require to process their…

    The Plane Highway in the Sky

    If you’ve ever looked at a flight tracker sometime around 10 or 11 pm eastern, you might have noticed something—perfect lines of planes stretching all the way to Europe. These are just some of the over 2,000 daily flights that cross the Northern Atlantic. With so many flights, there just has to be organization. This is the most direct route from New York to London. You may think it’s this, a straight line, but that straight line isn’t actually a straight line. This curved line is a straight line because, despite what some may think, the earth is curved. From New York to London the curve you see on a…

    9. Insect flight muscles

    Most insect species have wings as adults and are able to fly. Unlike birds and bats, insect wings are not modified fore limbs, but are extensions of the cuticle of the meso- and meta-thoracic segments. These two thoracic segments also have prominent muscles used for generating the wingbeat Flight muscles of bats and birds attach directly to the wings, and pull the wings up and down. In insects, only dragonflies and damselflies have muscles attached directly to the wing and these muscles only produce the downstroke for the wingbeat. In all other flying insects, both the downstroke and upstroke of the wingbeat are produced in response to contractions by muscles…
