Wing

A wing is a type of fin with a surface that produces aerodynamic forces facilitating movement through air and other gases, or water and other liquids. As such, wings have an airfoil shape, a streamlined cross-sectional shape producing lift.

The word "wing" from the Old Norse vængr for many centuries referred mainly to the foremost limbs of birds (in addition to the architectural aisle.) But in recent centuries the word's meaning has extended to include lift producing appendages of insects, bats, pterosaurs, boomerangs, some sail boats and aircraft, or the inverted airfoil on a race car that generates a downward force to increase traction.

Various species of penguins and other flighted or flightless water birds such as auks, cormorants, guillemots, shearwaters, eider and scoter ducks and diving petrels are avid swimmers, and use their wings to propel through water.

A wing's aerodynamic quality is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.

Under Attack

"Under Attack" is the last widely released single by Swedish pop group ABBA. It was originally featured as a track on the 1982 compilation album The Singles: The First Ten Years, but was released as a single the following year in most countries. However, in the United Kingdom it was released on 3 December 1982. "Under Attack" was ABBA's 28th single for Polar Music.

Background

Recording for "Under Attack" began between 2 and 4 August 1982 at Polar Music Studios, Stockholm. The group had originally intended to release a new studio album, but the stress of the working environment led them to indefinitely shelve the project and instead release a double-album compilation of their past singles. Since it was decided that there would be two new tracks on the compilation, ABBA set to work recording the songs. The two tracks that made it onto what became The Singles: The First Ten Years were "The Day Before You Came" and "Under Attack". The former was released as a single in October 1982. "Under Attack" contains fragments from two unreleased ABBA songs: "Just Like That" and "Rubber Ball Man", also known as "Under My Sun".
