Dornier Do 417. The Dornier Do 417 was a twin-engine multirole combat aircraft.  Developed in 1942, it resulted from the Luftwaffe's request for a medium bomber, a contest in which Dornier, Junkers, Heinkel, and Blohm & Voss competed.  In the end, the Junkers Ju 188 was chosen by the Luftwaffe, and the Do 417 never entered production.

Design and development 
The plans for the Do 417 were first presented to the RLM on January 22, 1943 in response to the Bomber B competition.  It was intended to fill both the bomber and reconnaissance roles. It was to have a stepless cockpit housing three of the four crew, and was to be fitted with Kuto-Nase cable-cutters on the nose and along the leading edge of the wing to defend against barrage balloons.  Dive brakes were to be positioned over and under the wings between the engine nacelles, similar to the Do 217.  The pilot's seat and tail gunner's positions were to be armored, and although unpressurized, the crew would have been able to operate at high altitude with oxygen masks.  The glazed nose and the propellers would have had de-icers, and inflatable one-man dinghies would have been provided in case the aircraft ditched in the sea.

Defensive armament was originally to have consisted of an MG 151 cannon in the nose, an HD 151 turret in the dorsal position, and another HD 151 in the tail.  The nose-mounted MG 151 was later changed to a small turret, and an MG 131Z machine gun was added to the underside of the nose.  It would have been fitted with a Lotfernrohr 7D bombsight.  The internal bomb load was limited to fifteen 50 kg bombs, but provisions were to be provided for two 2,000 kg bombs carried under the fuselage.  The aircraft was originally to be powered by two Junkers Jumo 222 engines, but problems with these led them to be substituted with the Daimler-Benz DB 603A inverted V12 engines, later changed to the DB 603G model.

However, the Do 417's performance was estimated to be worse than that of the competing Junkers Ju 188, and the Do 417 was rejected so the aircraft was never built.

Variants 
Do 417 V1
Unbuilt first prototype, to be powered by two DB 603A-2 engines.
Do 417A
Proposed production variant to be powered by two DB 603G engines.

National Forest Policy, 1988. The National Forest Policy, 1988 is an Act of the Parliament of India to revise the previously enacted National Forest Policy of 1952. The 1988 National Forest Policy strongly suggested the idea of empowering and involving local communities in the protection and development of forests. A direct outcome of the National Forest Policy, 1988 was the Joint Forest Management Program (JFM /JFMP) instituted in 1990 by the Government of India. It was started on a pilot project basis in West Bengal as early as 1971, and again in the late 1980s with considerable success.

History 
Several legislation in India focused on improving environmental quality since the enactment of the National Forest Policy of 1952. The Indian Parliament passed the Wildlife Protection Act, 1972, Water Act in 1974, Air Act, 1981, the Forest Conservation Act in 1980 and the Environment Protection Act in 1986.

Dornier Do 231. The Dornier Do 231 was a 1970s VTOL transport aircraft project developed by Dornier.

Design and development 
The Do 231 was a result of a design competition conducted in the early 1970s by the German Federal Ministry of Economics to create a 100-person VTOL transport aircraft. Based on the earlier Do 31, the Do 231 was to have shoulder-mounted cantilever swept wings and a T-tail.

The 1973 oil crisis rendered the Do 231 proposal as uneconomical due to the high fuel consumption necessary for vertical takeoff and landing, and the aircraft was cancelled in 1976 without a single prototype being built.

Variants 
Do 231C
Commercial variant for Lufthansa with a capacity of 100 passengers.
Do 231M
Military variant with a stretched fuselage and a rear loading ramp.

Hinduja Cargo Services Flight 8533. Hinduja Cargo Services Flight 8533 was a scheduled cargo flight from Tribhuvan International Airport in Nepal to Indira Gandhi International Airport in India operated by Lufthansa Cargo's Indian subsidiary Hinduja Cargo Services. On 7 July 1999, the Boeing 727 operating the flight crashed into Champadevi Hills at  altitude with no survivors amongst the 5 occupants on board.

Aircraft and crew 
The aircraft was a 17 year old Boeing 727-200 Freighter plane. It was delivered previously to Alitalia in 1981 as I-DIRS with Continental Airlines too operating the airframe as N586PE and N14416 before delivery to Hinduja Cargo Services as VT-LCI. There were 5 crew members on board, namely Gonjalez, Shahni, Vargava, Singh and Roy.

Flight 
The flight was carrying 21 tons of cargo, mostly textiles and carpets. The flight departed Runway 20 at Kathmandu's Tribhuvan International Airport. After take-off the flight made a 10-degree bank to the right for heading of 247 at 4.4DME. The power applied on the engines was inadvertently reduced so the aircraft lost height in area where altitude of any departing flight must be above  while VT-LCI was at . The Ground Proximity Warning System (GPWS) activated and sounded an alarm in the cockpit for 11 seconds. The speed was reduced to  causing the stick shaker to activate. VT-LCI impacted Champadevi Hills at 7:51 p.m. local time with no survivors.

Pensana Salt End. Pensana Saltend is a future processing facility for rare earth metals at Salt End, near Hull in the East Riding of Yorkshire, England. When operating at capability, the plant aims to produce 5% of world demand for neodymium and praseodymium oxide. Work on the site started in 2021, with full opening by 2023. The facility will be the first of its kind in Europe.

History
The facility will process rare earths from Angola in Africa, for downstream use in cars, phones, and wind turbines. In September 2021, Pensana confirmed a 25-year lease on the site at Saltend, with a view to providing between 100 and 125 permanent jobs at the plant by 2024. By the time of its operating capability, the plant is aiming to produce  of neodymium and praseodymium oxide per year; about 5% of global demand by 2025.

As most rare earth metals are processed in China, the facility would be the first of its kind in Europe. The site is located with the Humber Freeport, which launched in October 2021. The site will have the potential to expand and produce up to  of rare earth metals per year, most of which will be destined for the wind power markets. The intent is that 100% of power for the facility will come from the Dogger Bank Wind Farm via a direct link. The plant is seen as part of a growing concern regarding the supply of the minerals necessary for electric car batteries and wind turbines, as part of a de-carbonised economy. However, with China de-carbonising their industries, it is thought that rare earth metals will be subject to supply issues.

Pensana was formed in 2006, and Besides their future mining operations in Angola, Pensana are also mining for rare earths in Gabon. Pensana claim that their mining and quarrying processes are 'greener' than other mining companies.

In January 2022, a revised application was lodged with a different location some  to the north-east and covering an area of . The application also sought to allow for the storage of hydrochloric acid, sodium hydroxide and oxalic acid. In May 2022, East Riding councillors approved the application which will cover over .

Lida-class minesweeper. The Lida-class minesweeper, Soviet designation Project 10750 Code name: Sapfir ( for Sapphire, NATO - designation: Lida) is a class of small minesweeper of the Soviet and Russian navies, which was developed to search for sea mines in port entrances, ports and rivers. Nine vessels were built by the Soviet Union and later by Russia from 1986 for the Russian Navy. Since then, the construction of eight more has started.

Description

Hull and sonar 
The hulls of Project 10750 are made of fiberglass, have a double bottom and are divided into nine watertight compartments.

To search for underwater contacts, a dome with a Kabarga-A1 sonar is built into the hull. On the aft of the ship there is a working platform on which a 5.3-tonne crane is mounted, with which the search robot and minesweeping gear can be brought in and out.

Armament 
 
The boats are armed with a 30 mm turret AK-306 on the forecastle. In addition, two Strela-2 anti-aircraft missiles can be used against flying targets. Four sea mines along with KIU-1 Luch or KIU-2M Anakonda mine searcher-and-destroyer or GKT-3-MO contact sweep, AT-6 acoustic sweep or SEMT-1 electromagnetic sweep, AT-6 acoustic sweep or 2x200 meters of the detonation cord can be carried.

Export 
 
In addition to project 10750, the variant Project 10750E MCM was planned for export to Kazakhstan, of which at least one boat was built. The boats are equipped with two  MAN D2866 diesels instead of the three engines on the Russian boats, have only two propellers, carry different sensors and communication equipment and are equipped with two 12.7 mm Kord machine guns armed.

Whereabouts 
Nine Project 10750 boats were completed for the Russian Navy by 1996; the construction of six boats is said to have started since then. Originally 26 ships were planned, but were never started due to financing problems. Two boats were decommissioned until 2014.

Vickers Boxkite. The Vickers Boxkite refers to three aircraft built by Hewlett & Blondeau and a single similar aircraft actually built by Vickers was created by Vickers Aviation. Originally, Vickers used their own monoplanes  at their flying school at Brooklands. In late 1912 the school bought three Farman-type aircraft from Hewlett & Blondeau, who also had a flying school at Brooklands. These three aircraft were modified to become the Vickers Boxkite. The Vickers constructors numbers given to these aircraft were No. 19, 20, and 21.

The first two aircraft were powered by a 50 hp Gnome engine while the third was powered by a 70 hp Gnome engine. Two of the aircraft were eventually taken by the Royal Flying Corps.

In 1913, Vickers built a version of these aircraft with equal-span wings and a rudimentary nacelle. It was initially powered by a Vickers-Boucier 50 hp engine, later replaced with a 70 hp Gnome engine.
