With a number of unfortunate plane accidents happening over the past few years (for some info on the most recent incident... http://www.vingle.net/posts/651245), I've gotten curious about how planes are made, how they work, and how that all plays into the amazing fact that as many flights happen without problem every day.
The first video here is a video covering the basics of how a plane is made. It covers the production of an Airbus A350, and includes some ideas about how the engineers work to figure out how to create and manufacture the plane. Make sure to look at the plane-that-carries-planes a.k.a. the Beluga!
The next video is about the aerodynamics of flight. Not the most spirited video, but if you really want to know how huge jet aircrafts work, then this is the video for you. Now, this isn't enough to build a plane, but it covers the basics as a good starting point for further info about how aircrafts work.
The last video is about how air traffic control works. A big part of why people get so worried about flying comes down to things like too many planes in the air (will we hit?), is there going to be a storm, and who would tell us where to land if we can't land where originally planned? This video is a small introduction by NATS, the British service for air traffic control. The video focuses on how the service works coming in and out of Heathrow, but the principles can be applied around the world.
These three videos are only a small part of the puzzle that is aviation and air travel. The millions of flights that travel the world each year are a testament, I think, to how advanced technology has become, as well as monitoring systems, and it's beyond impressive that there are not more incidents each year. Still, there is always room for improvement...
What else about aviation are you curious to know?
