Mail Rocket
Rocket mail is the delivery of mail by rocket or missile. The rocket lands by deploying an internal parachute upon arrival. It has been attempted by various organizations in many countries, with varying levels of success. It has never become widely seen as being a viable option for delivering mail, due to the cost of the schemes and numerous failures. The collection of philatelic material ("stamps") used for (and depicting) rocket mail is part of a specialist branch of aerophilately known as astrophilately. Pioneers German author Heinrich von Kleist was the first to suggest using rockets to deliver mail. While editor of the ''Berliner Abendblätter'', he wrote an article published on 12 October 1810 which proposed using fixed artillery batteries to fire shells filled with letters to predetermined landing locations of soft ground. Kleist calculated that a network of batteries could transmit a letter from Berlin to Breslau, away, in half a day. Later in the 19th century, Con ...

Regulus Missile
The SSM-N-8A Regulus, also known as the Regulus I and RGM-6, is a nuclear-capable turbojet-powered second generation cruise missile operated by the US Navy between 1955 and 1964. Its development was an outgrowth of U.S. Navy tests conducted with the German V-1 missile at Naval Air Station Point Mugu in California. Its barrel-shaped fuselage resembled that of numerous fighter aircraft designs of the era, but without a cockpit. Test articles of the Regulus were equipped with landing gear and could take off and land like an airplane.''Regulus: The First Nuclear Missile Submarines'' documentary, Spark, 2002 When the missiles were deployed they were launched from a rail launcher, and equipped with a pair of Aerojet JATO bottles on the aft end of the fuselage. History Design and development Background Nazi Germany's use of the V-1 flying bomb during World War II marked the first combat deployment of a cruise missile, highlighting the potential of a new class of weapon.

Envelope
An envelope is a common packaging item, usually made of thin, flat material. It is designed to contain a flat object, such as a letter (message), letter or Greeting card, card. Traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross or a Kite (geometry), kite. These shapes allow the envelope structure to be made by folding the sheet sides around a central rectangular area. In this manner, a rectangle-faced enclosure is formed with an arrangement of four flaps on the reverse side. Overview A folding sequence such that the last flap closed is on a short side is referred to in commercial envelope #Manufacture, manufacture as a pocket – a format frequently employed in the packaging of small quantities of seeds. Although in principle the flaps can be held in place by securing the topmost flap at a single point (for example with a wax seal), generally they are pasted or gummed together at the overlaps. They are most commonly u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

Scotland
Scotland is a Countries of the United Kingdom, country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent Islands of Scotland, islands, principally in the archipelagos of the Hebrides and the Northern Isles. To the south-east, Scotland has its Anglo-Scottish border, only land border, which is long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The population in 2022 was 5,439,842. Edinburgh is the capital and Glasgow is the most populous of the cities of Scotland. The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of Kingdom of England, England and Kingdom of Ireland, Ireland, forming a personal union of the Union of the Crowns, three kingdo ...

Scarp, Scotland
Scarp () is an uninhabited island in the Outer Hebrides of Scotland, west of Hushinish on Harris. Once inhabited, the island was the scene of unsuccessful experiments with rocket mail, since commemorated in two films. Geography Scarp has an area of , divided into 16 crofts. The majority of the land is rocky and uncultivated, and is dominated by two hills, of which the higher reaches . There is a small area of low-lying fertile land in the south-east corner of the island, and here, closest to Harris, is where the inhabitants of the island once lived. The population of Scarp peaked at 213 in 1881, and as recently as the 1940s it was reported to be over 100. The island was settled by eight farming families in 1810, and the population rose, following clearances on Harris, to over two hundred. This population could not be supported as there is little cultivatable land and no all-weather harbour, resulting in many families drifting away. Even in the 1950s the economy was still b ...

Outer Hebrides
The Outer Hebrides ( ) or Western Isles ( , or ), sometimes known as the Long Isle or Long Island (), is an Archipelago, island chain off the west coast of mainland Scotland. It is the longest archipelago in the British Isles. The islands form part of the archipelago of the Hebrides, separated from the Scottish mainland and from the Inner Hebrides by the waters of the Minch, the Little Minch, and the Sea of the Hebrides. The Outer Hebrides are considered to be the traditional heartland of the Gaelic language. The islands form one of the 32 council areas of Scotland, which since 1998 has used only the Gaelic form of its name, including in English language contexts. The council area is called Na h-Eileanan an Iar ('the Western Isles') and its council is ('Council of the Western Isles'). Most of the islands have a bedrock formed from ancient metamorphic rocks, and the climate is mild and oceanic. The 15 inhabited islands had a total population of in and there are more th ...

Sussex Downs
The South Downs are a range of chalk hills in the south-eastern coastal counties of England that extends for about across the south-eastern coastal counties of England from the Itchen valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate, East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs, and includes large parts of the Weald. The national park is the UK's most visited, attracting an estimated 39 million visitor-days annually. The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England. The South Downs are relatively less populated compared to South ...

General Post Office
The General Post Office (GPO) was the state postal system and telecommunications carrier of the United Kingdom until 1969. Established in England in the 17th century, the GPO was a state monopoly covering the dispatch of items from a specific sender to a specific receiver (which was to be of great importance when new forms of communication were invented); it was overseen by a Government minister, the Postmaster General. Over time its remit was extended to Scotland and Ireland, and across parts of the British Empire. The GPO was abolished by the Post Office Act 1969, which transferred its assets to the Post Office, so changing it from a Department of State to a statutory corporation. Responsibility for telecommunications was given to Post Office Telecommunications, the successor of the GPO Telegraph and Telephones department. In 1980, the telecommunications and postal sides were split prior to British Telecommunications' conversion into a totally separate publicly owned c ...
