The London Underground is the world's first and oldest rapid transit system, opening in 1863.
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electricrailways, that unlike buses or trams operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles.
Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on railway tracks. Some systems use guided rubber tires, magnetic levitation (maglev), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by the same public transport authorities. Some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. (Full article...)

The Eurocopter AS 350 Ecureuil ("Squirrel") and AS 355 Ecureuil 2 are a family of light helicopters originally manufactured by Aérospatiale (now part of Eurocopter Group). The AS 350 (marketed as the AStar in North America) is the single-engined version, while the AS 355 (TwinStar) uses two engines. The EC 130B is a recent adaptation of the AS 350 airframe.
