Norman B. Hall. Norman Brierley Hall (1 September 1886 – 26 April 1962) was an engineering officer in the United States Coast Guard who became the first aviation engineer in the Coast Guard in 1916.

Hall was born at New York City on 1 September 1886 and graduated from high school in Brooklyn, New York in 1903. He then attended the Webb Academy of Marine Engineering and Naval Architecture, graduating in June 1906. Hall worked at a Hoboken, New Jersey shipyard as a general draftsman for fifteen months before becoming a cadet engineer in the U.S. Revenue Cutter Service on 21 October 1907. He was commissioned a third lieutenant of engineers on 4 September 1908.

Hall was promoted to second lieutenant of engineers on 5 January 1911. He was assigned to  on 11 August 1914. While serving there, he discussed the possibility of using aircraft to aid search and rescue missions with his commander Captain Benjamin M. Chiswell and Third Lieutenant Elmer F. Stone. With Chiswell's encouragement, Commandant Ellsworth P. Bertholf sent Hall to study aircraft design, construction and maintenance at the Curtiss Aeroplane and Motor Company factory in Hammondsport, New York on 31 October 1916.

Hall was promoted to first lieutenant of engineers on 26 April 1921 and then to lieutenant commander on 12 January 1923. From April 1928 to May 1933, he was head of aviation engineering activities at Coast Guard headquarters. On 1 July 1929, he was promoted to commander.

On 23 September 1938, Hall was promoted to captain. In June 1942, he was made chief of the Port Security Division. In August 1942, Hall was given the additional assignment of Coast Guard liaison to the Facility Security Division of the Office of the Petroleum Coordinator for War. In July 1943, he was also made a member of the Merchant Marine Council. On 25 November 1944, Hall was promoted to commodore. Early in 1945, he replaced James A. Hirshfield as vice chairman of the Merchant Marine Council. Hall was awarded the Legion of Merit for his World War II service.

At the time of his retirement on 1 November 1947, Hall was promoted to rear admiral.

Hall died on 26 April 1962 in Bethesda, Maryland. He was interred at Green-Wood Cemetery in Brooklyn, New York next to his first wife Elizabeth (Hamilton) Hall (6 October 1892 – 8 October 1951). He had remarried with a widow, Gladys Marsh Footner, in 1954 and they were living in Chevy Chase, Maryland at the time of his death.

McDonnell Douglas Phantom in UK service - data. A total of 185 F-4 Phantoms were produced for and operated by the United Kingdom between 1968 and 1992. Between 1966 and 1969, 170 Phantoms were specially built for the UK, replacing the de Havilland Sea Vixen in the fleet air defence role for the Royal Navy, and the Hawker Hunter in the close air support and tactical reconnaissance roles in the Royal Air Force. Subsequently, when replaced by the SEPECAT Jaguar for close air support and reconnaissance, the Phantom replaced the English Electric Lightning as the UK's primary air defence interceptor. The Phantom was operated by the Royal Navy until 1978, when , the only British ship capable of operating the aircraft, was decommissioned. Following this, the Royal Navy's Phantoms were turned over to the Royal Air Force. In 1984, a batch of 15 former United States Navy and United States Marine Corps Phantoms were obtained by the Royal Air Force to form an additional squadron. The Phantom began to be replaced by the air defence variant of the Panavia Tornado from 1987, and was finally withdrawn from service in 1992.

Italian frigate Aliseo (F 574). Aliseo (F 574) is the fifth ship of the Maestrale-class frigate of the Italian Navy.

Development  
The Maestrale-class frigates were primarily designed for anti-submarine warfare (ASW), however the ships are highly flexible so they are also capable of anti-air and anti-surface operations. Ships of this class have been widely used in various international missions, either under NATO or UN flag, and during normal operations of the Italian Navy.

The first of these ships entered in service in early 1982. The rest of the fleet was launched over the next three years. The ships of the Maestrale class will be replaced by the Bergamini class.

Construction and career 
She was laid down on 26 February 1980 and launched on 29 October 1982 by Fincantieri shipyards. Commissioned on 20 September 1983 with the hull number F 574. She was decommissioned on 8 September 2017. Scrapped in Aliaga Turkey 2022.

Saxon M I TV. The Saxon class M I TV was a class of two German 0-4-4-0 Meyer tank locomotives built for the Royal Saxon State Railways ()

History 
In 1890, the Sächsische Maschinenfabrik in Chemnitz developed a Günther-Meyer articulated locomotive for operation on the winding branch lines of the Ore Mountains. However, only two locomotives with the serial numbers 1658 and 1659 were built. The two locomotives were given the fleet numbers 822 and 823 and the names RASCHAU and CROTTENDORF. 

Initially, they were classified as H M I TV. From 1896 they were then called M I TV; from 1900 they were referred to as I TV.

The locomotives did not prove themselves, so initially no further locomotives of this type were procured. The locomotives tended to run unevenly, especially at higher speeds. In addition, there was an increased tendency to slip when starting. Similar locomotives were procured for the Saxon narrow-gauge railways as class IV K from 1892.

It was only after the turn of the century that powerful and particularly curvy locomotives were needed for the  near Dresden that locomotives of the same type were built. However, these differed significantly from the original design (see Saxon I TV).

The two M I TV locomotives were withdrawn from service in 1922, and the Deutsche Reichsbahn gave them no new numbers.

Technical features 
The locomotives had a two-ring boiler with a Crampton firebox. Two non-lifting Friedmann injectors were used to feed the boiler

The steam circuit was designed as a four-cylinder compound drive with Walschaerts valve gear (Heusinger) and flat slide valves. The smaller high-pressure cylinders were on the rear bogie, the larger low-pressure cylinders on the front bogie. The bogies were connected by a coupling iron in order to reduce any counter-rotating movements.

The water supply was housed in side tanks. The coal was located in a bunker behind the driver's cab.

The locomotives originally only had a steam brake as braking equipment, supplemented by a counterweight brake. Westinghouse air brakes were later retrofitted.

As special equipment, they were provided with a Latowski-type of steam-driven bell.

Windrose 5.5. The Windrose 5.5 is  an American trailerable sailboat that was designed by W. Shad Turner as a pocket cruiser and first built in 1977.

The Windrose 5.5 was developed from the Windrose 18 and was developed into the Laguna 18 in 1983.

Production
The design was built by Laguna Yachts in Stanton, California, United States, but it is now out of production.

Design
The Windrose 5.5 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig with a deck-stepped mast and aluminum spars. The hull has a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a fixed fin shoal-draft keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel allowing ground transportation on a trailer.

The boat is normally fitted with a small  outboard motor for docking and maneuvering.

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two quarter berths under the cockpit. The head is located just aft of the companionway steps and is a portable type. Ventilation is provided by a hatch on the foredeck. Cabin headroom is .

The design has a PHRF racing average handicap of 288 and a hull speed of .

Operational history
In a 1994 review Richard Sherwood wrote that the, "Windrose is designed as a little cruiser and has bunks for four, with a double berth forward and two quarter berths. Space remains for cabin seating, shelf storage, and a head. This shoal-draft boat has 500 pounds of ballast in the keel. The manufacturer claims that the special shape of the keel makes Windrose track unusually well."

In a 2010 review Steve Henkel wrote, "by 1980 the design trend was toward wider boats, for extra stability as well as cabin space. Laguna Yachts and Shad Turner responded by widening the six-year-old Windrose 18 ... from seven feet to eight feet, and introducing a number of other changes. Principal among these were (a) eliminating the potentially troublesome steel centerboard and substituting instead a shallow iron-filled keel, and (b) rearranging the cabin space for more elbow room. For example, the portable head was moved aft where its use wouldn't interfere with V-berth sleepers; the settee berths in the '18' were replaced by wider quarter berths and a central seating area. Best features: The new design eliminates worry over centerboard difficulties, and provides more elbow room. Worst features: The fixed keel is too shallow to give good sailing performance compared to the Windrose 18's (despite the fact that PHRF rating for both the 18 and the 5.5 is—unfairly—identical at 288), and the keel makes launching and retrieving at a launching ramp considerably more difficult than with her comps or with the shallower-draft '18'."

Winchester city walls. Winchester city walls are a series of defensive walls in central Winchester, originally built during the Roman settlement of southern Britain, in what was then the settlement of Venta Belgarum. The area surrounding Winchester had been populated throughout the Iron Age, with Britonnic settlements existing at Oram's Arbour, St Catherine's Hill, and Worthy Down; Venta Belgarum took its name from the Belgae tribes of the area. Earthwork defences were constructed around the end of the second century, being rebuilt in stone during the latter part of the third century..

Under Saxon rule, Alfred the Great rebuilt Winchester and its defences as part of the burh system developed to protect against Norse incursions. Winchester was later chosen as the location of one of the first Norman castles in England, with Winchester Castle being built alongside the walls in 1067. As well as the royal castle in the West of the city, Wolvesey Castle, the palace of the Bishop of Winchester, was built in the East of the City alongside the River Itchen; during the Civil War known as The Anarchy, the forces of Queen Matilda, on behalf of King Stephen, besieged the forces of Empress Matilda, destroying much of the old city including the urban defences, in an event known as the Rout of Winchester.

Whilst Winchester's city walls went through periods of decline, by the 14th century, the city had 6 gates, the West Gate, South Gate, King's Gate, East Gate, North Gate and Durn Gate. In the English Civil War, the city was seized on behalf of the King by royalist Sir William Ogle, before being captured by Parliamentary forces led by Sir William Waller; the city was subsequently recovered by the Royalist forces before being recaptured by Parliament after the Battle of Cheriton, after which much of the castle was demolished, apart from the Great Hall.

During the 18th century, much of the walls and gates were demolished due to the relatively low height of the gates and their hazards to pedestrians, with the Eastgate demolished in 1768, and the Southgate demolished from 1771. The Northgate also collapsed in 1756. Today only the Kingsgate and Westgate survive, with other portions of the wall existing around the gates and Winchester Castle, as well as alongside the Itchen by the remains of Wolvesey Castle, with other sections having been demolished or repurposed. Sections of the wall remain as listed and protected areas.
