List of UFO religions: UFO religions are groups which deal with alleged communication between humans and extraterrestrial beings.  Forms of communication include telepathy and astral projection.  Groups often believe that humanity can be saved after being educated by the aliens as to how to improve society.  Alien abduction belief can lead to formation of a UFO religion.  I AM Religious Activity, founded in 1930 by Guy Ballard, is seen, according to one author, as the first UFO Religion, though Aetherius Society founded by George King has also been given this distinction.  Scholars identify the 1947 Roswell UFO Incident as a key event within the history of UFO spirituality.  Melodie Campbell and Stephen A. Kent describe Heaven's Gate and Order of the Solar Temple as among the most controversial of the UFO belief groups.  Scientology is seen by scholars as a UFO religion, due to its Xenu cosmogony and the presence of Space opera in Scientology doctrine.

Gloster Meteor: The Gloster Meteor was the first British jet fighter and the Allies' only jet aircraft to achieve combat operations during the Second World War.  The Meteor's development was heavily reliant on its ground-breaking turbojet engines, pioneered by Sir Frank Whittle and his company, Power Jets Ltd.  Development of the aircraft began in 1940, although work on the engines had been under way since 1936.  The Meteor first flew in 1943 and commenced operations on 27 July 1944 with No. 616 Squadron RAF.  The Meteor was not a sophisticated aircraft in its aerodynamics, but proved to be a successful combat fighter.  Gloster's 1946 civil Meteor F.4 demonstrator "G-AIDC" was the first civilian-registered jet aircraft in the world.

Upper Rissington: Upper Rissington is a village and civil parish in the Cotswold district of Gloucestershire, England.  It is located about two-and-a-half miles east of Bourton-on-the-Water and is one of the highest villages in the Cotswolds at an elevation of 275 m.  The village is on the former site of the Central Flying School and the airfield is still the active RAF site of RAF Little Rissington.  Some of its housing was built as officers' quarters from the 1930s to the 1950s.  These were sold by the Ministry of Defence in 1996 to developers, who modernised the properties and sold them on.  The street names give a clue to the village's former life, having names such as Sopwith Road and Avro Road.  The village has since been greatly expanded with many new houses built on the site of the old RAF hangers and ancillary buildings.  Several of the buildings of architectural importance such as the Station HQ and the Officers Mess have been retained and converted into housing.  The village is enhanced by the large numbers of mature trees planted by the first Station Commander which are now all protected.
