Pisces- class submersibles are three-person research deep-submergence vehicles designed and built by Hyco International Hydrodynamics of North Vancouver in British Columbia with a maximum operating depth of 2,000 m (6,560 ft). The vehicles have multiple view ports and sample collecting, environmental sensing, and instrument placement capabilities. The pressure hull has a 7 ft (2.1 m) inside diameter and is made of HY-100 steel with three forward-looking acrylic windows, 6 in (15 cm) in diameter. Designed by Allan Trice , the Pisces series of submersibles were representative of crewed submersibles built in the late 1960s and were proven workhorses in offshore exploration and oceanographic research . Pisces II was the first production model of the design and was completed in 1968, with nine more Pisces submarines built before the manufacturer went out of business in the late 1970s.

It sank to the bottom of the ocean with its two-man crew, Britons Roger Mallinson and Roger Chapman, stranded at a depth of 1,575 feet (480 m) and 72 hours of available life support, which they were able to extend to 76 hours by careful conservation. Initial rescue efforts by Pisces III sister submersibles were unsuccessful. Through an international effort of

In 1830 mail was carried by train for the first time, on the newly-opened Liverpool and Manchester Railway ; over the next decade the railways replaced mail coaches as the principal means of conveyance (the last mail coach departed from London on 6 January 1846). The first Travelling Post Office (TPO)

In the mid-1960s the GPO was asked by the government to expand into banking services which resulted in the creation of the National Giro in 1968. When new forms of communication came into existence in the 19th and early 20th centuries the GPO claimed monopoly rights on the basis that like the postal service they involved delivery from

By this decree, Thomas Witherings (who had been appointed 'Postmaster of England for foreign parts' three years earlier) was empowered to provide for the carriage of private letters at fixed rates 'betwixt London and all parts of His Majesty's dominions'. To this end,
420-483: A sender and to a receiver . The theory was used to expand state control of the mail service into every form of electronic communication possible on the basis that every sender used some form of distribution service. These distribution services were considered in law as forms of electronic post offices. This applied to telegraph and telephone switching stations. In 1846, the Electric Telegraph Company ,

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 corporation the following year as a result of the British Telecommunications Act 1981 . In 1986
588-659: A bell to attract custom was adopted by the Post Office and went on to be employed in major cities until the mid-19th century. In 1761 permission was given for the establishment of penny-post arrangements elsewhere in the realm, to function along the same lines as the London office, if they could be made financially viable; by the end of the century there were penny-post systems operating in Birmingham, Bristol, Dublin, Edinburgh and Manchester (to be joined by Glasgow and Newcastle-upon-Tyne in
672-621: A court ruling obliged the London Penny Post to come under the authority of the Postmaster General. Although now part of the GPO, the London Penny Post continued to operate entirely independently of the General (or 'Inland') Post until 1854 (when the two systems were combined). An attempt by Charles Povey to set up a rival halfpenny post in 1709 was halted after several months' operation; however Povey's practice of having letter-carriers ring
756-532: A fee. The trade in these 'ship letters' was acknowledged (and legitimised) in the Post Office Acts of 1657 and 1660. Attempts were made to levy Post Office fees on these letters and 'ship letter money' was offered to captains for each letter given to a postmaster on arrival in England in order for these charges to be applied; however they were under no legal obligation to comply and the majority of ship letters evaded
840-430: A hand bell. While postmasters were not obliged to deliver items to places outside the boundary, they could agree to do so on payment of an extra fee. In the 1780s, Britain's General Post network was revolutionised by theatrical impresario John Palmer 's idea of using mail coaches in place of the longstanding use of post horses. After initial resistance from the postal authorities, a trial took place in 1784, by which it

Many letters went by foot-post rather than on horseback. Footposts or runners were employed by many towns, cities and other communities, and had been for many years. A 16th-century footpost would cover around 30 miles per day, on average. At the time of

In the following century, packet services out of Falmouth began to sail to the West Indies, North America and other transatlantic destinations. Packet boats, however, were not the only means of conveying letters overseas: there had always been the option of sending them by merchant ship, and coffee houses had long been accustomed to receiving letters and packages on behalf of ships' captains, who would carry them for

' Packet boats ', offering a regular scheduled mail service, were already in use for the passage between Holyhead and Dublin; but for letters to and from the Continent the post was entrusted to messengers, who would make their own travel arrangements. This

The long-established practice of 'riding post' was acknowledged through the provision of four seats inside the coach for passengers. The mail bags were carried in a locked box at the back, above which sat a scarlet-coated guard. While the coaches and coachmen were provided by contractors, the guards worked for the Post Office. As well as two pistols and

To begin with the Post Office was again farmed, nominally to Henry Bishop , but the deal was bankrolled by John Wildman (a gentleman of dubious repute, who kept a tight rein on his investment). Two years later Wildman was imprisoned, implicated in a plot against the King, whereupon Bishop sold
1596-738: The Leeward Islands was enjoined. The Irish post at this time operated as part of the GPO under a Deputy Postmaster General based in Dublin; but in 1784 an Act was passed by the Parliament of Ireland providing for an independent Post Office in Ireland under its own Postmaster General (an arrangement that remained in place until 1831). The established post roads in Britain ran to and from London. The use of other roads required government permission (for example, it

(The separate Postmaster General appointments were consolidated in 1637, but the 'foreign' and 'inland' postal services remained separate in terms of administration and accounting until the mid-19th century). It was not until 1635 that a general or public post was properly established, for inland letters as for foreign ones. On 31 July that year, King Charles I issued

In 1801 the cost of posting a letter within the central London area was doubled; thenceforward the London District Post was known as the 'Two-penny Post' until its amalgamation into the General Post 53 years later. During the reign of King William III , the General Post Office created a network of 'receiving-houses', in London and the larger provincial towns, where senders could submit items. A Scottish Post Office

By 1863, 2,500 post offices were offering a savings service . Gradually more financial services were offered by post offices, including government stocks and bonds in 1880, insurance and annuities in 1888, and war savings certificates in 1916.

At first the new postal network was not especially well publicised; but in his 1673 publication Britannia , Richard Blome sought to remedy this by describing in some detail the geographical disposition of the new 'general Post-Office' , which he called an 'exceeding great conveniency' for
6300-413: Was charged for items posted or delivered in the surrounding 'country' area (which included places such as Hackney, Newington, Lambeth and Islington). The Penny Post letter-carriers operated from seven main sorting offices around London, which were supplemented by between four and five hundred 'receiving houses' in all the principal streets in the area, where members of the public could post items. (Prior to
6384-436: Was demonstrated that a mail coach departing from Bristol at 4pm would regularly arrive in London at 9 o'clock the following morning: a day and a half quicker than the post horses. As a result, the conveyance of letters by mail coach, under armed guard, was approved by Act of Parliament. Mail coaches were similar in design to the passenger-carrying stage coaches , but were smaller, lighter and more manoeuvrable (being pulled by
6468-539: Was established in 1695 (although the post-road to Edinburgh continued to be managed from London); in 1710 the Scottish and English establishments were united by statute . By virtue of the same Act of Parliament (the Post Office (Revenues) Act 1710 ), the functions of the 'general letter office and post office' in the City of London were set out, and the establishment of 'chief letter offices' in Edinburgh, Dublin, New York and
6552-487: Was far from reliable, so in the 1630s Thomas Witherings set about establishing a regular Dover-Calais packet service. By the end of the century additional packet services had been established between Harwich (off the Yarmouth post road) and Helvoetsluys , between Dover and Ostend / Nieuport , and between Falmouth and Corunna . The packet services were generally arranged by contract with an agent, who would commit to provide
6636-408: Was introduced in 1837, and these began to be widely used enabling mail to be sorted in transit; TPO operation was greatly aided by the invention in 1852 of a trackside ' mail-bag apparatus ' which enabled bags to be collected and deposited en route . By the 1860s the Post Office had contracts with around thirty different rail companies. The development of marine steam propulsion inevitably affected
6720-417: Was introduced in 1848, and parcel post in 1883; that same year the term 'letter-carrier' was replaced with ' postman ' in the GPO's official nomenclature. By the 1850s the postal system was described as having become 'universal all over the three kingdoms: no village, however insignificant, being without its receiving-house'. In 1855 a network of 920 post offices and 9,578 sub-offices were in place around
6804-434: Was only after much lobbying that a 'cross-post' between Bristol and Exeter was authorised, in 1698; previously mail between the two cities had to be sent via London). In 1720 Bath postmaster Ralph Allen , who had a vision for improving the situation, took over responsibility for the cross-posts (i.e. routes connecting one post road to another) and bye-posts (connecting to places off the main post roads). He greatly expanded
6888-548: Was slightly damaged by a German bomb in 1917 and in 1940, was set alight during the London Blitz , destroying much of the interior. It reopened in 1943. By the 1950s, the volume of telegraph traffic had declined and the Telegraph Office closed in 1963. In 1984 the new British Telecom Centre was opened on the site. The Post Office commenced its telephone business in 1878, however the vast majority of telephones were initially connected to independently run networks. In December 1880,
6972-487: Was taken out of Royal Mail Group, prior to the latter's privatisation in 2013. The privatised holding company (Royal Mail plc) was renamed International Distributions Services plc in 2022. In the medieval period, nobles generally employed messengers to deliver letters and other items on their behalf. In the 12th century a permanent body of messengers had been formed within the Royal Household of King Henry I , for
7056-449: Was to provide the horses; he would also provide a guide to accompany the messenger as far as the next post house (and then see to the return of the horses afterwards). In practice most post-houses were established at roadside inns and the innkeeper served as postmaster (in return for a small salary from the Crown). At Dover merchant ships were regularly employed to convey letters to and from
