Flight

Flight is the process by which an object moves, through an atmosphere (the air in the case of earth) or beyond it (as in the case of spaceflight) without direct support from any surface. This can be achieved by generating aerodynamic lift, propulsive thrust, aerostatically using buoyancy, or by ballistic movement.

Many things fly, from natural aviators such as birds, bats and insects to human inventions such as missiles, aircraft such as airplanes, helicopters and balloons, to rockets such as spacecraft.

The engineering aspects of flight are studied in aerospace engineering which is subdivided into aeronautics, the study of vehicles that travel through the air, and astronautics, the study of vehicles that travel through space, and in ballistics, the study of the flight of projectiles.

Types of flight

Buoyant flight

Humans have managed to construct lighter than air vehicles that raise off the ground and fly, due to their buoyancy in air.

An aerostat is a system that remains aloft primarily through the use of buoyancy to give an aircraft the same overall density as air. Aerostats include free balloons, airships, and moored balloons. An aerostat's main structural component is its envelope, a lightweight skin containing a lifting gas to provide buoyancy, to which other components are attached.

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.

Wonder Woman

Wonder Woman is a fictional superhero appearing in American comic books published by DC Comics. The character is a warrior princess of the Amazons (which are based on the Amazons of Greek mythology) and is known in her homeland as Princess Diana of Themyscira. When outside her homeland, she is sometimes known by the secret identity Diana Prince. She is gifted with a wide range of superhuman powers and superior combat and battle skills. She possesses an arsenal of weapons, including the Lasso of Truth, a pair of indestructible bracelets, a tiara which serves as a projectile, and (in older stories) a range of devices based on Amazon technology.

Wonder Woman was created by the American psychologist and writer William Moulton Marston. The character first appeared in All Star Comics #8 in December 1941 and first cover-dated on Sensation Comics #1, January 1942. The Wonder Woman title has been published by DC Comics almost continuously except for a brief hiatus in 1986. Her depiction as a heroine fighting for justice, love, peace, and gender equality has led to Wonder Woman being widely considered a feminist icon. Created during World War II, the character was initially depicted fighting Axis military forces as well as an assortment of colorful supervillains, although over time her stories came to place greater emphasis on characters, deities, and monsters from Greek mythology. In the decades since her debut, Wonder Woman has gained a formidable cast of enemies bent on eliminating the Amazon, including classic villains such as Ares, Cheetah, Circe, Doctor Psycho, and Giganta, along with more recent adversaries such as the First Born. Wonder Woman has also regularly appeared in comic books featuring the superhero teams Justice Society (from 1941) and Justice League (from 1960).
