USS AFDM-2. USS AFDM-2, (former YFD-4), is an  medium auxiliary floating drydock built in Mobile, Alabama by the Alabama Drydock and Shipbuilding Company for the U.S. Navy. Originally named USS YFD-4, Yard Floating Dock-4, she operated by Todd Shipyards at New Orleans, Louisiana for the repair of US ships during World War II. YFD-4 was renamed an Auxiliary Floating Dock Medium AFDM-2 in 1945 after the war.

Design 
AFDM-2 was  tall,  wide, length of  (all three section connected), and has a displacement of 6,360 tons. AFDM-2 could lift capacity 9,000 tons and had two service cranes to lift material and parts for removing damage parts and the installation of new parts. The floating drydock can repair ships up to a beam of , as she is 90 feet wide between the wing walls.  Ballast pontoons tanks are flooded with water to submerge or pumped dry to raise the ship. Submerged she can load a ship with a draft up to .

History
It was built by Alabama Drydock and Shipbuilding Company in Mobile, Alabama. she was laid down in January 1942 and commissioned on 1 October 1943, right after her delivery to the Navy.

Hurricane Betsy, Category 4, sank and damaged AFDM-2 on 9 September 1965. USS AFDM-2 was at Todd Shipyards on the west side of the Mississippi River in Algiers, New Orleans. AFDM-2 had the water pumped out of her pontoon tanks and was raised for repair. The salvage ships MS Cable and  and , an Achomawi-class fleet ocean tug, helped in the recovery of AFDM-2. Due to the large size of AFDM-2 two rescue and salvage ships,  and  arrived with three special support barges to help in the salvage. Land-based winches were also used in the recovery. On 25 August 1966 tugs returned AFDM-2 to Todd Shipyards, eleven months after her sinking. Repairs where completed and she was put back in service. Divers had to repair more than 100 holes in AFDM-2 to float her again.

On 16 May 1995 she was laid up in the National Defense Reserve Fleet, Beaumont, Texas. On 11 February 1999 she was reactivated and transferred to the Government of the Dominican Republic. She was later sold to Gulf Copper & Manufacturing Corporation at Port Arthur, Texas and renamed Mr. Morris. In 2013 , a landing ship, tank, now a  museum ship, was repaired in AFDM-2. On 17 December 2021, USS Orleck (DD-886) arrived in Port Arthur to be repaired in AFDM-2.

Arado E.654. The Arado E.654 was a German heavy fighter project by Arado Flugzeugwerke, its design created by Arado's Chief Designer Walter Blume.

Design
Designed by Walter Blume, E.654 used a widened variant on the fuselage of the Arado Ar 240 so that it could mount two DB 614 or DB 627 engines inside the fuselage, similar to the Arado E.561. It had a single vertical tailfin with a tailplane. Like the E.561, it was abandoned due to technical issues with the transmission to the wings. It used straight wings with tapering on leading and trailing edges. It used three wheels with a tricycle arrangement, all of which could retract into their specific parts of the aircraft. The cockpit was located between the nose, and had two crew members sitting back-to-back.

Brunswick-Balke-Collender OQ-4. 

The Brunswick-Balke-Collender OQ-4 was a prototype drone built in the United States by the Brunswick-Balke-Collender corporation.

The OQ-4 was one of a very few aviation-related ventures undertaken by Brunswick-Balke-Collender, which was basically a non-aviation company. It was similar in some respects to the Radioplane OQ-2, including a 12-foot wingspan. Although a few prototypes were built, the OQ-4 was not put into production, perhaps because Radioplane and Frankfort could produce enough target drone so that another production line was not necessary.

Lascurain Aura. The Lascurain Aura was a prototype of a regional aircraft designed and built for Mexican engineer Angel Lascurain. It was the largest aircraft designed and built in Mexico.

Development 
Lascurain wanted to manufacture an aircraft designed for the regional airlines of some parts of Mexico that required connecting populations in very rugged geographical areas that had no access to any other type of transport than the aerial and the rugged terrain caused the airstrips to be very short for the American and European aircraft of those times.

Lascurain determined that regional airlines required a twin-engine plane with fixed landing gear that was accessible (since foreign aircraft cost more than one million pesos and airlines could not pay for them), capable of landing at low speed on short runways. The aircraft had to have a high rate of climb to overcome the mountainous areas.

In 1955 Ángel Lascurain went with the architect Juan Cortina Portilla, beginning the design of the aircraft based on the turkey buzzard, a bird for which Lascurain felt fascination.

Design 
The aircraft was a twin-engine monoplane with a mid-wing monocoque fuselage built in duralumin that was capable of holding 12 people in 2 rows of 6 seats plus a bathroom lobby, with the option of 14 seats without the bathroom, all this without counting the two pilots. The fuselage was part of the wings through beams that extended to the ends of the same, this in order to protect passengers and pilots in case of accident. Each wing had between the engine and the fuselage 2 compartments for luggage of 0.65 cubic meters each, the aircraft had 2 tanks of fuel of 200 liters each that fed to the Jacobs R-755 engines by means of gravity and pumps besides 2 tanks auxiliaries located at the ends of the wings of 50 liters each.

Accident 
On December 24, 1957, during a routine flight of the plane Lascurain Aura with license plate XB-ZEU at the Mexico City Airport for no apparent reason, both engines of the aircraft were stopped and the pilot attempted to land at the airport. planning until the runway 13, nevertheless they did not reach to arrive at the track, crashing in a board of earth a few meters before the head of the same one, killing the pilot Carlos Castillo Segura and Angel Lascurain.

Naleszkiewicz JN-1. The Naleszkiewicz JN-1 was an experimental tailless sailplane designed in Poland  to explore the aerodynamic properties of a proposed powered tailless aircraft. It proved hard to fly and a crash led to its abandonment after only a few months of limited testing.

Design and development
Jarosław Naleszkiewicz's Naleszkiewicz JN-1, nicknamed Żabuś II (Froggy II; the Jach Żabuś was an earlier, unrelated Polish glider) was an experimental tailless glider which was intended to test the behaviour of a proposed twin-engined aircraft of the same configuration. It was preceded by a series of rubber-powered models which proved flight stability and suggested good performance.

In essence the wooden JN-1 was a high aspect ratio, cantilever wing with a short, bulbous central nacelle and wingtip vertical surfaces. Its two part wing was trapezoidal in plan, with most of the sweep on the leading edge. Each part was built around a single spar with plywood covering ahead of it, forming a torsion resistant D-box, and fabric covering behind. Control surfaces filled the whole trailing edge, with elevators inboard and ailerons outboard.

The cockpit was within a ply-covered nacelle which reached forward from the trailing edge to well ahead of the leading edge. Its glazing provided good sideways, but limited forward, vision. A pneumatically-sprung skid under the nacelle provided the JN-1's landing gear.

At the wingtips endplate fins carried balanced rudders. Together these vertical surfaces had an elliptical profile, cropped and reinforced below the wing to protect it on the ground. The rudders could be used conventionally in unison or in opposition as airbrakes.

Operational history
The JN-1 first flew on 23 July, rubber rope launched and flown by Franciszek Jach in Dęblin. It proved to be hard to control, being oversensitive in pitch both via elevator control and centre of gravity position. Car-towed flights follows but the control difficulties persisted and in the autumn the JN-1 was damaged in a crash. It was not repaired because of a mixture of funding problems, a lack of official interest and Naleszkiewicz's absence due to a new job in Warsaw.

With its differentially operating rudders it may have the first glider fitted with air-brakes, though of a very different type to the spoilers used a few years later on German sailplanes.

Blackhillock Substation. Blackhillock Substation is an electrical substation located in the north east of Scotland, near the town of Keith in Moray.

It is owned and operated by Scottish Southern Electricity Network (SSEN).  Covering an area the size of 24 football pitches, it is as of January 2019, the UK's largest substation and Europe's second biggest.

Construction began in early 2015 to upgrade the existing substation so it could accommodate the new 1,200 MW Caithness - Moray Link. The £1bn construction project had four main elements: 400kV and 132kV gas-insulated substations, one 275kV air-insulated substation, a High Voltage Direct Current (HVDC) converter for the Caithness - Moray subsea link and a HVDC underground cable from the substation to Portgordon.  In January 2019 construction and commissioning were completed making it the UK's largest operating substation.  It is seen as integral to the UK electricity grid as the north of Scotland generates much renewable energy via windfarms. The upgrade was primarily done to accommodate the Beatrice Windfarm.

A 300 MW / 600 MWh grid battery started construction at the site in 2023.

William Cable & Company. William Cable & Company was a heavy engineering business in Kaiwharawhara, Wellington, New Zealand established as the Lion Foundry in 1856 by Edward William Mills. In 1881 Mills took in William Cable as a partner and in 1883 Cable bought him out.

Their business included the supply and manufacture of structural steel, industrial machinery, ferrous and non-ferrous castings, galvanising, boiler making, ship repair and maintenance, electrical engineering services, electrical jib and overhead cranes.

William Cable & Company joined with Auckland region founders and engineers A & G Price in 1951 to form Cable-Price Corporation; now owned by Hitachi Construction Machinery.

The Lion Foundry

Edward William Mills
This business was established by E. W. Mills (1829–1900) in 1856 in Aurora Terrace (later the site of his large house Sayes Court, beside the Wellington Club on The Terrace) as the Lion Foundry. The foundry, which by then employed 120 men, was moved in March 1871 to reclaimed land by the harbour at Waring Taylor Street extending to Customhouse Quay about 1872. Steamers and locomotives were built and repaired on the waterfront site. Major contracts were undertaken for railways, shipping, tramways, sawmills and the like.

William Cable
William Cable (1848–1922) was appointed foundry manager in 1872 then became a partner of E W Mills. The business operated under the name Mills & Cable. C M Luke and John Luke were on the foundry staff at this time. Wellington's first telephone — without an exchange — was installed by Mills in 1878 between his various business premises. Cable took full ownership of Lion Foundry in 1883.

Cable-Price
The merchandising interests of Cable's and its foundry were merged with A & G Price in 1951 and Cable Price Corporation was incorporated. It is now a subsidiary of Hitachi Construction Machinery.

E W Mills and Briscoe

Mills sold out to Cable to devote his time and money to E W Mills & Co, his substantial ironmongery business he had founded earlier in 1854 in Lambton Quay and now also with a second warehouse in Featherston Street, which stocked bulk-oils, galvanised iron safes and strong-room doors, stoves bedsteads and bolts and nuts and many other items, agricultural equipment and machinery, operated a ships chandlery and supplied customers across the whole country.

In 1932 Briscoe and Co whose business was also hardware and iron and steel merchants amalgamated with — then family-controlled by an 80 per cent shareholding — E W Mills to form Briscoe E W Mills each owning half the capital. The Mills name was dropped and the business is now known as Briscoe Group. Briscoe E. W. Mills and Company Limited changed its name to Briscoes (New Zealand) Limited 29 September 1961.
