Sentetsu Shiki class railcars: The Shiki or Sigeu (Japanese シキ, Korean 시그) class railcars were a class of 3rd class steam railcars of the Chosen Government Railway ("Sentetsu").  There were two classes of such railcars, one built in Japan and one built in the United Kingdom.

Elmore Houses: The Elmore Houses are a pair of historic farmhouses at 78 and 87 Long Hill Road in South Windsor, Connecticut.  The two houses, one built before 1819 and restyled in the 1840s, and the other one built new in the 1840s, are locally important rural examples of Greek Revival architecture.  They were listed on the National Register of Historic Places in 1985.

Unmanned spacecraft: Unmanned spacecraft are spacecraft without people ("man") on board, used for unmanned spaceflight.  Unmanned spacecraft may have varying levels of autonomy from human input, they may be remote controlled, remote guided or even autonomous, meaning they have a pre-programmed list of operations, which they will execute, unless otherwise instructed by the Earth.  Many habitable spacecraft also have varying levels of robotic features.  For example, the space stations Salyut 7 and Mir, and the ISS module Zarya were capable of unmanned remote guided station-keeping, and docking maneuvers with both resupply craft and new modules.  The most common unmanned spacecraft categories are robotic spacecraft, unmanned resupply spacecraft, space probes and space observatories.  Not every unmanned spacecraft is a robotic spacecraft, for example a reflector ball is a non-robotic unmanned spacecraft.

Toili: Toili is a district in the Banggai Regency of Central Sulawesi, Indonesia.  It is a largely agricultural area with palm oil plnations, gold mining, and gas and petroleum production.  Transmigration policies have brought people from Java, Nusa Tenggara and Bali.

Douglas DC-8: The Douglas DC-8 (also known as the McDonnell Douglas DC-8) is a four-engine long-range narrow-body jet airliner built from 1958 to 1972 by the Douglas Aircraft Company.  Launched after the competing Boeing 707, the DC-8 nevertheless kept Douglas in a strong position in the airliner market, and remained in production until 1972 when it began to be superseded by larger wide-body designs, including the Boeing 747, McDonnell Douglas DC-10 and Lockheed L-1011 TriStar.  The DC-8's design allowed it a slightly larger cargo capacity than the 707 and some re-engined DC-8s are still in use as freighters.

Succoth-benoth: Succoth-benoth or Succoth Benoth (Hebrew: סֻכּוֹת בְּנוֹת,  " ",  " " ; ) ""Booths of Daughters" "was a Babylonian deity, one of the deities brought to the former kingdom of Samaria (Israel) by "the men of Babylon" after the exile of Israel by Assyria.  After resettling large numbers of Israel's population "in Halah, in Gozan, on the Habor River and in towns of the Medes" (2 Kings 18:11), the king of Assyria brought people from Babylon, Cuthah, Avva, Hamath and Sepharvaim" and settled them in Israel.  (From the intermixture of these peoples and the remaining Israelites came the Samaritans.)

Sentetsu Nakeha class railcars: The Nakeha (Japanese ナゲハ, Korean 혀게하) class railcars were a group of 3rd class narrow-gauge petrol-powered railcars of the Chosen Government Railway ("Sentetsu").  There were two classes of such railcars, one built in Japan and one built in Korea.  After Liberation, they all remained in the South, where they were operated by the Korean National Railroad; none were preserved.

Xenu: Xenu ( ), also called Xemu, was, according to Scientology founder L. Ron Hubbard, the dictator of the "Galactic Confederacy" who 75 million years ago brought billions of his people to Earth (then known as "Teegeeack") in DC-8-like spacecraft, stacked them around volcanoes, and killed them with hydrogen bombs.  Official Scientology scriptures hold that the thetans (immortal spirits) of these aliens adhere to humans, causing spiritual harm.

Revolt in the Stars: Revolt in the Stars is a science fiction film screenplay written by Scientology founder L. Ron Hubbard in 1977.  It tells the space opera story of how an evil galactic dictator, named Xenu, massacres many of his subjects by transporting them to Earth and killing them with atomic bombs.  L. Ron Hubbard had already presented this story to his followers, as a true account of events that happened 75 million years ago, in a secret level of Scientology scripture called Operating Thetan, Level III.  The screenplay was promoted around Hollywood circles in 1979, but attempts at fundraising and obtaining financing fell through, and the film was never made.  Unofficial copies circulate on the Internet.

Culture of Thalassery: The British had considerable impact on local culture.  As an ancient trade center, the trading and business relations that existed with the Europeans and the Arabs brought people and ideas from many other lands.  The Christian missionaries and the educational reforms they brought played an important role in transforming society.  The migration to Travancore during Hyder Ali and Tipu Sultan's invasion was another factor, resulting in less social distance between upper and lower castes from the 18th to mid-20th centuries.  This effect did not reach the Travancore Cochin area, which was not under the Madras Presidency, where inequality was greater.
