The Royal Air Force (RAF) is the aerial warfare service branch of the British Armed Forces. Formed on 1 April 1918, it is the oldest independent air force in the world. The RAF has taken a significant role in British military history, playing a large part in the Second World War and in more recent conflicts.

The RAF is one of the most capable and technologically sophisticated air forces in the world. As of January 2012^[update] it operated 827 aircraft, making it the largest air force of a European Union country and the second largest in NATO (after the USAF). Most of the RAF's aircraft and personnel are based in the UK, with many others serving on operations (principally Afghanistan and the Middle East) or at long-established overseas bases (Ascension Island, Cyprus, Gibraltar, and the Falkland Islands).

The RAF's mission is to support the objectives of the British Ministry of Defence (MoD), which are to "provide the capabilities needed: to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government’s foreign policy objectives particularly in promoting international peace and security."

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy or other branch. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions and providing support to surface forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation within a national air force. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as antiaircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an Air Defence Force which is organizationally separate from their air force.

Monty Python (sometimes known as The Pythons) was a British surreal comedy group who created Monty Python's Flying Circus, a British television comedy sketch show that first aired on the BBC on 5 October 1969. Forty-five episodes were made over four series. The Python phenomenon developed from the television series into something larger in scope and impact, spawning touring stage shows, films, numerous albums, several books and a stage musical as well as launching the members to individual stardom. The group's influence on comedy has been compared to The Beatles' influence on music.

The television series, broadcast by the BBC from 1969 to 1974, was conceived, written and performed by members Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin. Loosely structured as a sketch show, but with an innovative stream-of-consciousness approach (aided by Gilliam's animation), it pushed the boundaries of what was acceptable in style and content. A self-contained comedy team responsible for both writing and performing their work, the Pythons' creative control allowed them to experiment with form and content, discarding rules of television comedy. Their influence on British comedy has been apparent for years, while in North America it has coloured the work of cult performers from the early editions of Saturday Night Live through to more recent absurdist trends in television comedy. "Pythonesque" has entered the English lexicon as a result.
