List of X-planes

The X-planes are a series of experimental United States airplanes and helicopters (and some rockets) used to test and evaluate new technologies and aerodynamic concepts. Most of the X-planes have been operated by the National Advisory Committee for Aeronautics (NACA) or, later, the National Aeronautics and Space Administration (NASA), often in conjunction with the United States Air Force. The majority of X-plane testing has occurred at Edwards Air Force Base.

Some of the X-planes have been well publicized, while others, such as the X-16, have been developed in secrecy. The first, the Bell X-1, became well known after it became, in 1947, the first aircraft to break the sound barrier in level flight. Later X-planes supported important research in a multitude of aerodynamic and technical fields, but only the North American X-15 rocket plane of the early 1960s achieved comparable fame to that of the X-1. X-planes 7 through 12 were actually missiles used to test new types of engines, and some other vehicles were un-manned (some were remotely flown, some were partially or fully autonomous).

Homecoming (Heroes)

"Homecoming" is the ninth episode of the first season of the NBC science fiction drama series Heroes.

Plot

The episode begins with Claire and her friend Zach walking into the high school amphitheater with lunch as Claire's former cheerleader friends wait anxiously for the results of the Homecoming Court vote. Claire downplays the entire ritual, but Zach encourages her to check the posting and see if she had won. To Claire's surprise, she has been voted Homecoming Queen, with her main rival, Jackie, merely a member of the court. Astonished, Claire and the rest of the cheerleaders turn around to see much of the student body proclaiming congratulations and support for Claire. She later discovers that Zach had been campaigning for her, working to win the "unpopular vote" by letting everyone know that Claire is not like the popular Jackie. Jackie, however, spoils the moment in an attempt to deflate Claire's victory by poking fun at Zach. Claire, beginning to see the importance of Zach's friendship to her, promptly punches Jackie in the face.

HTML element

An HTML element is an individual component of an HTML document or web page, once this has been parsed into the Document Object Model. HTML is composed of a tree of HTML elements and other nodes, such as text nodes. Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Many HTML elements represent semantics, or meaning. For example, the title element represents the title of the document.

In the HTML syntax, most elements are written with a start tag and an end tag, with the content in between. An HTML tag is composed of the name of the element, surrounded by angle brackets. An end tag also has a slash after the opening angle bracket, to distinguish it from the start tag. For example, a paragraph, which is represented by the p element, would be written as

However, not all of these elements require the end tag, or even the start tag, to be present. Some elements, the so-called void elements, do not have an end tag. A typical example is the br element, which represents a significant line break, such as in a poem or an address. A void element's behaviour is predefined, and it cannot contain any content or other elements. For example, the address of the dentist in the movie Finding Nemo would be written as
