AirUK: Air UK was a wholly privately owned, independent regional British airline formed in 1980 as a result of a merger involving four rival UK-based regional airlines. British and Commonwealth (B&C)-owned British Island Airways (BIA) and Air Anglia were the two dominant merger partners.  The merged entity's corporate headquarters were originally located at Redhill, Surrey, the location of the old BIA head office.  It subsequently relocated to Crawley, West Sussex.  In addition to the main maintenance base at Norwich Airport (Air Anglia's former engineering base), there also used to be a second major maintenance base at Blackpool Airport (the old BIA engineering base).  This was closed down following Air UK's major retrenchment during Britain's severe recession of the early 1980s.  In 1987, Air UK established Air UK Leisure as a charter subsidiary.  The following year, Air UK shifted its headquarters to London Stansted Airport.  When Stansted's new Norman Foster-designed terminal opened in 1991, the airline became its first and subsequently main tenant.

Privately owned public space: Privately owned public space (POPS), or alternatively, privately owned public open spaces (POPOS), are terms used to describe a type of public space that, although privately owned, is legally required to be open to the public under a city's zoning ordinance or other land-use law.  The acronym POPOS is preferentially used over POPS on the west coast of the US.  Both terms can be used to represent either a singular or plural space or spaces.  These spaces are usually the product of a deal between cities and private real estate developers in which cities grant valuable zoning concessions and developers provide in return privately owned public spaces in or near their buildings.  Privately owned public spaces commonly include plazas, arcades, small parks, and atriums.  Many cities worldwide, including Auckland, New York City, San Francisco, Seattle, Seoul, and Toronto, have privately owned public spaces.  Some cities and advocacy groups have created websites about these spaces (see, for example, apops.mas.org).
