The Air and Space Magazine is a publication of the Smithsonian National Air and Space Museum. This special series of the magazine provides insight into various aspects of aerospace principles and technology. Three articles in this section can be accessed, despite the listing of all seven. First is an overview of winglets on airplanes, describing their purpose and how they increase performance. The second article looks at "devices an aerobatic airplane uses to defy gravity." Lastly, ejection seats are the topic of the final article. There are supplements and additional features given on the magazine's home page, but full text is not available for all articles.
