Sibsey Trader Mill. Trader Mill is located in the village of Sibsey, Lincolnshire. It's one of two windmills which were grinding flour for the local community. Rhodes Mill (the second of the two) has been converted into a house.  Built in 1877 by Saunderson of Louth in the typical Lincolnshire style, since then it has been restored and is now owned by English Heritage and managed by an independent party. It is a six-storey windmill with complete gear, six sails and fantail which still works today. It is a Grade I listed building.

The windmill is one of the very few six-sailed mills still remaining in England.
The mill itself is not exceptionally tall and in fact stands only six floors high above ground and the height to the top of the mill's cap is a mere 74 feet 3 inches. However the slenderness of the tower combined with the flat landscape which surrounds the mill give the illusion that Sibsey is larger than it actually is. The slim central tower also makes the sails look enormous in comparison.

The mill worked until 1954 (although with only four sails in its later years) following which it was allowed to fall into disrepair. It has now been restored to full working order and today produces a wide range of organic flours.

The mill features in the CBeebies series Baby Jake where location filming for the series took place in the late summer of 2010.

Mitsubishi 2MR8. The Mitsubishi Army Type 92 Reconnaissance Aircraft (九二式偵察機) (company designation 2MR8) was a Japanese short-range reconnaissance aircraft of the 1930s designed by Mitsubishi  for the Imperial Japanese Army Air Force. A total of 230 were built, serving  between 1933 and 1936. A parasol monoplane, the Type 92 was the first military aircraft powered by an engine both designed and manufactured in Japan to enter service.

Development and design
In 1930, Mitsubishi developed two designs to meet a Japanese Army requirement for a short-range reconnaissance aircraft to supplement the larger, long-range Kawasaki Type 88, the 2MR7, a biplane based on its earlier 2MR reconnaissance aircraft and B2M torpedo bomber developed for the Imperial Japanese Navy, and the 2MR8, a high-wing parasol monoplane.

The first of four prototypes flew on 28 March 1931, powered by a 239 kW (320 hp) Mitsubishi A2 radial engine. Successive prototypes were modified with more powerful engines, reduced wing area and a shorter fuselage until the fourth prototype was accepted by the Japanese Army, and ordered into service as the Type 92 Reconnaissance Aircraft.

The production Type 92 had fixed wide-track divided landing gear, and was powered by a 354 kW (450 hp) Mitsubishi Type 92 radial engine. It carried a crew of two in open cockpits, with an armament of two synchronised, forward-firing 7.7 mm (.303 in) machine guns and one or two flexibly-mounted guns on the observer's cockpit. Production completed in 1934 after a total of 230 aircraft were built.

To meet the requirements of the Japanese Ministry of Railways for a survey aircraft, Mitsubishi developed a civilian version of the Type 92, the Hato survey aircraft. A single aircraft was ordered in 1935, together with a Fokker Super Universal built by Nakajima. Powered by a 298 kW (400 hp) Mitsubishi A5 engine, it differed from the military version in having a glazed canopy over the rear cockpit (which accommodated a crew of two), an open forward pilot's cockpit, and spat-type main wheel fairings. It was delivered in March 1936 and registered J-AARA.

Operational history
The Type 92 saw active service in Manchuria with the air battalions (later expanded to air wings) of the Kwantung Army Air Corps between 1933 and 1936. The Mitsubishi Type 92 was also used by the Chinese Air Force in the early stages of the Second Sino-Japanese War.

Operators

Kwangsi Air Force purchased two Type 92s in September 1934, with a few more being purchased in 1935.

Charles Richards (NASA engineer). Charles Richard was a design engineer, who designed the collapsible four-tube Rogallo wing used in the experimental NASA Paresev glider. The wing configuration he created was used for manned hung-pilot kite-gliders and was to be found copied only with slight ornamental variation in a decade of hang gliders. Richards was of the Flight Research Center's Vehicle and System Dynamics Branch. The four-beamed wing folded from the nose plate; one of the beams was the spreader beam that kept the flexible-wing's sweep. Those in the following decade copying the Charles Richard wing configuration expanded kiting, hang gliding, ultralight, and trike flight.

Timeline 

 1961 December : Charles Richard is given a directive from NASA's Paul Bikle to build quickly a cheap kite glider that could be used to give pilots practice in flying in free flight using simple weight-shifting that would change the attitude of the wing relative to the hung position of the pilot and payload.
 1962 February 12 : Charles Richard and his team completed a first kite-glider that achieved obtaining an FAA registration. Many versions followed first flight tests.
 2004 Charles Richard name was included in the space Stardust (spacecraft) chip. .

USCGC Swivel. USCGC Swivel (WYTL-65603) was one of fifteen 65-foot steel-hulled harbor tugs, that entered service with the United States Coast Guard in the 1960s. Each was built to replace the 64-foot wooden-hulled harbor tugs built during the 1940s.

Ship history
USCGC Swivel was built by the Gibbs Gas Engine Company of Jacksonville, Florida, at a cost of $158,000. She was commissioned on 27 October 1961. The 65-footers remained unnamed until the mid-1960s.  Swivel was assigned to the First Coast Guard District and was based in Rockland, Maine. Her crew consisted of an Officer in Charge (OINC), a Chief Boatswain Mate (E-7); an Executive Petty Officer (XPO), a First Class Boatswain Mate (E-6); an Engineering Petty Officer (EPO), a First Class Machinist Mate (E-6); a Second Class Machinist Mate (E-5) and three non-rated crew (E-3 or E-2).

Swivel's area of operation was mainly Penobscot Bay and extended westward to Whitehead Lighthouse, easterly to Saddleback Ledge and northward through East Penobscot Bay, Castine, and up the Penobscot River to the city of Bangor, Maine. Swivels operations throughout the year included domestic icebreaking, aids to navigation, search and rescue, marine environmental protection, maritime law enforcement and commercial fishing vessel safety.

Swivel's main mission in the summer months was to maintain more than fifty fixed (non-floating) Coast Guard aids to navigation, including five lighthouses. During the winter months the Swivel kept local harbors free of ice and spent a week in rotation with two other cutters keeping the Penobscot River open to navigation for fuel barges that transported home heating fuel, gasoline and aviation fuel to Bangor and the surrounding communities.

Swivel received a Coast Guard Unit Commendation and two Meritorious Unit Commendations for her missions, along with the Coast Guard Unit Commendation presented to all 1st Coast Guard District units involved with the 1994 ice season.

Swivel was decommissioned at a ceremony held at the pier in Rockland, Maine, on 14 April 1995.

As part of the Coast Guard's closing of its base on Governors Island in New York City, the Swivel was brought down as a passenger and work boat for the Coast Guard and U.S. General Services Administration base closure staff.

As of 2015 Swivel is now a service and staff boat owned by the Trust for Governors Island, which is redeveloping the former Coast Guard base at Governors Island, New York City, and is operated by HMS Global Maritime.

Lioré et Olivier LeO H-43. 

The Lioré et Olivier LeO H-43 was a reconnaissance seaplane produced in France in the 1930s. It was a strut-braced, mid-wing monoplane of largely conventional design, provided with an observation balcony underneath the fuselage. It was designed to be launched by catapult from warships and, after a first flight in 1934, trials were conducted on board Commandant Teste.

Development was prolonged and the prototype underwent much modification before an order for 20 machines was placed by the Aéronavale. Even after this, a major redesign to the forward fuselage was specified as part of the production order. As a result, the first test flight of the production version did not take place until 13 July 1939, by which time the H-43 was already obsolete.

The twenty examples purchased briefly equipped two squadrons from February 1940, but all were withdrawn with the Fall of France.

Lioré et Olivier LeO H-47. 

The Lioré et Olivier LeO H-47 was a flying boat airliner built in France in 1936. It was designed to operate passenger services over the South Atlantic, but the outbreak of the Second World War caused the type to be used by the French Navy as a maritime patrol aircraft.

Development and design
In 1934, the French air ministry issued a specification for a long-range flying boat to be used by Air France on services over the South Atlantic between Dakar in Senegal and Natal in Brazil. As such, the specification required that the new transport be capable of flying  at a speed of  while carrying a payload of . Lioré et Olivier received an order for a prototype of its design to meet this specification, the LeO H-47 on 10 August 1935.

The H-47 was a cantilever high-wing monoplane, with a streamlined hull. A flight deck, which accommodated a crew of five (two pilots, a navigator, a radio operator and a mechanic) and a cabin for four to eight passengers were fully enclosed within the aircraft's hull. The four  Hispano Suiza 12Y engines were mounted in two tractor-pusher pairs above the wing.

The prototype H-47 first flew from Antibes on 25 July 1936, and was destroyed in a crash in May 1937 that was attributed to a wingtip float breaking away whilst the aircraft was in flight. Nevertheless, Air France went ahead with the purchase of five similar (though strengthened) machines, designated H-470, which were put into service as mail planes. These machines were impressed into the French Navy at the outbreak of the Second World War.

The four remaining aircraft remained in use with the Vichy French Navy following the French Armistice, serving as transports between France and Tunisia, before being transferred to Dakar in Senegal in June 1941. The last H-470 was scrapped in August 1943 when stocks of spares ran out.

Fleurs Aerodrome. Fleurs Aerodrome was a parent aerodrome built on behalf of the Royal Australian Air Force during World War II. It is located at Kemps Creek 40 km west of Sydney, Australia

Construction started on the aerodrome in 1942 and was still under construction in 1944 as part of a proposal to base a United States Navy Fleet Air Wing in Sydney should the need arise. Initially planned with three runways, No.1 (5000 ft) and No. 3 (6000 ft) runways were serviceable, however construction of No. 2 runway (5000 ft) was abandoned. A total of eight aircraft dispersal hideouts were constructed and accommodation was a farm house and a former Civil Constructional Corps camp.

In 1969, Fleurs was considered as a site of a second airport for Sydney to operate scheduled passenger flights, which were only done by one other airport in the city, Kingsford Smith. The aerodrome is now utilised as precision ground-reflection antenna range operated by the University of Sydney, known as the Fleurs Radio Observatory.

Signal regeneration. In telecommunications, signal regeneration is signal processing that restores a signal, recovering its original characteristics.

The signal may be electrical, as in a repeater on a T-carrier line, or optical, as in an OEO optical cross-connect.

The process is used when it is necessary to change the signal type in order to transmit it via different media. Once it comes back to the original medium the signal is usually required to be regenerated so as to bring it back to its original state.

Raymond W. Ketchledge. Raymond Waibel Ketchledge (December 8, 1919 – October 23, 1987) was an American engineer, known for his contributions to the first computerized telephone switching control systems.

Biography
Born in Harrisburg, Pennsylvania, Ketchledge married Lois Jane Quackenbush. He earned a B.Sc. and M.Sc. (1942) in electrical engineering from the Massachusetts Institute of Technology before joining Bell Labs where he stayed for his whole professional career (1942–1982).

At Bell Labs he first worked on the Mark 24 FIDO Torpedo used in World War II, then took part in developing the first underwater repeater systems and the L3 coaxial carrier for Transatlantic telephone cable systems (1946–1954), before becoming the leader of the Switching systems development group (1956).  This brought him fame due to the pioneering work on applying stored program architecture to telephone switching systems.  Ketchledge oversaw the installation project for the first 1ESS switch in Succasunna (1965).

Following this he directed the Indian Hill laboratories of Naperville, Illinois (1966–1975), before returning to New Jersey where he oversaw the Ocean systems research division in Whippany, New Jersey, until his retirement. He held sixty patents in diverse areas, including thirty-one in switching systems.

He died of cancer at his home in Englewood, Florida, on October 23, 1987.
