Great Fountain, Enville to conceive. This, the large fountain, is on a level with the surface of the lake, and composed of five jets, the central one throwing a column of water 150 feet high; the supply being obtained from a large reservoir on the hill, to which it is first pumped by the united action of two engines, each of thirty horsepower.". The water continued to jet for several minutes, until the water in the reservoir was exhausted. The Great Fountain was the early ancestor of similar fountains located in lakes or bays, such as the Jet d'Eau in Geneva, Switzerland, which
Diamond D-Jet D-JET. The landing gear is electrically-actuated on later-built prototypes; atypically, the landing gear is designed to be used as an air brake during landing approaches, being deployable at speeds as high as 200 knots. Manoeuvring on the ground was achieved via a nosewheel steering system, actuated via a mechanical linkage to the pedals. According to Diamond, the D-JET could be operated from 3,000-foot runways, ensuring that they are both dry and uncontaminated. Diamond D-Jet The Diamond D-JET is a composite, five-seat, single-engine Very light jet developed by Austrian aircraft manufacturer Diamond Aircraft Industries. The intended cost for the aircraft was
