San Francisco

San Francisco (/sæn frənˈsɪskoʊ/), officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California and the only consolidated city-county in California. San Francisco encompasses a land area of about 46.9 square miles (121 km²) on the northern end of the San Francisco Peninsula, which makes it the smallest county in the state. It has a density of about 18,187 people per square mile (7,022 people per km²), making it the most densely settled large city (population greater than 200,000) in the state of California and the second-most densely populated major city in the United States after New York City. San Francisco is the fourth-most populous city in California, after Los Angeles, San Diego and San Jose, and the 13th-most populous city in the United States—with a Census-estimated 2014 population of 852,469. The city and its surrounding areas are known as the San Francisco Bay Area, and are a part of the larger OMB designated San Jose-San Francisco-Oakland combined statistical area, the fifth most populous in the nation with an estimated population of 8.6 million.

San Francisco International Airport

San Francisco International Airport (IATA: SFO, ICAO: KSFO, FAA LID: SFO) is an international airport 13 miles (21 km) south of downtown San Francisco, California, United States, near Millbrae and San Bruno in unincorporated San Mateo County. It has flights to points throughout North America and is a major gateway to Europe and Asia.

SFO is the largest airport in the San Francisco Bay Area including all of Northern California and the second busiest in California, after Los Angeles International Airport. In 2014, it was the seventh busiest in the United States and the twenty-fifth busiest airport in the world by passenger count. It is the fifth largest hub for United Airlines and functions as United Airlines's primary transpacific gateway. It also serves as Virgin America's principal base of operations. It is the sole maintenance hub of United Airlines, and houses the Louis A. Turpen Aviation Museum and Library.

SFO is owned and policed by the City and County of San Francisco, but is actually in San Mateo County. Between 1999 and 2004 the San Francisco Airport Commission operated city-owned SFO Enterprises, Inc., to oversee its business purchases and operations of ventures.

International airport

An international airport is an airport that offers customs and immigration facilities for passengers travelling between countries. International airports are typically larger than domestic airports and often feature longer runways and facilities to accommodate the heavier aircraft commonly used for international and intercontinental travel. International airports often also host domestic flights. Some, such as Frankfurt Airport in Germany are very large; others such as Fa'a'ā International Airport in Tahiti, are quite small.

Buildings, operations and management have become increasingly sophisticated since the mid 20th century, when international airports began to provide infrastructure for international civilian flights. Detailed technical standards have been developed to ensure safety and common coding systems implemented to provide global consistency. The physical structures that serve millions of individual passengers and flights are among the most complex and interconnected in the world. By the second decade of the 21st century, there were over 1,200 international airports and almost two billion international passengers along with 50 million metric tonnes of cargo were passing through them annually.

Francisco

Francisco is the Spanish and Portuguese form of the masculine given name Franciscus (corresponding to English Francis).

In Spanish, people with the name Francisco sometimes are nicknamed "Paco": San Francisco de Asís was known as Pater Comunitatis (The Community father) when he founded the Franciscan order, "Paco" is a short form of "Pater Comunitatis". Also, in Spanish Latin America and in the Philippines, people with the name Francisco are called "Pancho". "Kiko" is also used as a nickname in the Philippines.

In Portuguese, people named Francisco are commonly nicknamed "Chico" (shíco) or "Kiko". This is also a less-common nickname for Francisco in Spanish too.

Airport

An airport is an aerodrome with facilities for flights to take off and land. Airports often have facilities to store and maintain aircraft, and a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals. Larger airports may have fixed base operator services, airport aprons, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services.

An airport with a helipad for rotorcraft but no runway is called a heliport. An airport for use by seaplanes and amphibious aircraft is called a seaplane base. Such a base typically includes a stretch of open water for takeoffs and landings, and seaplane docks for tying-up.

An international airport has additional facilities for customs and immigration.

In warfare, airports can become the focus of intense fighting, for example the Battle of Tripoli Airport or the Battle for Donetsk Airport, both taking place in 2014. An airport primarily for military use is called an airbase or air station.
