Light Helicopter Experimental. The Light Helicopter Experimental (LHX) program was a 1980s United States Army helicopter procurement project to replace the AH-1 Cobra and OH-58 Kiowa helicopters. The result of this program lead to the development of the RAH-66 Comanche, which was cancelled before entering production.

Background
In support of the LHX program, the United States Army started the Advanced Composite Airframe Program (ACAP) to develop an all-composite helicopter fuselage. In February 1981, contracts were awarded to Sikorsky (for the Sikorsky S-75) and Bell Helicopter (for the Bell D-292).

LHX program
An Army Aviation Mission Area Analysis, completed in 1982, identified deficiencies in current materiel and doctrine that needed to be addressed to meet the requirements of the new Airland Battle Doctrine. The specific material deficiencies were to be resolved through the LHX program.

In 1982, the U.S. Army started the Light Helicopter Experimental (LHX) program to replace the UH-1, AH-1, OH-6, and OH-58 helicopters. In August 1986, the Defense Science Board review revealed that the Army suffered from stovepiping in a program development sense, and could not think outside the box. The Army solidified requirements too early without sufficient risk management. A single-crew version was an early requirement, but depended upon successful development of a risky electronic package.

Early concepts included both utility and scout/attack versions, but by 1988, the utility concept was dropped.  A Request for proposals for the new helicopter type was released in June 1988. In October 1988, the Boeing-Sikorsky and Bell-McDonnell Douglas teams received contracts for their designs. The Bell-McDonnell Douglas design featured ordnance carriage within a combined wing/sponson and instead of a tail rotor used a NOTAR ducted exhaust system. The Boeing-Sikorsky design carried ordnance within upward swinging gull-wing doors in the sides of the fuselage and featured a fenestron tail rotor. The program's name was changed to Light Helicopter (LH) in 1990. In April 1991, the Boeing-Sikorsky team was selected as the contest winner and received a contract to build four prototypes. Also that month, the helicopter was designated "RAH-66 Comanche" by the Army.

In March 2004, the Army Chief of Staff terminated the Comanche program.  The termination happened for several reasons; among them were unrealistic and unachievable overarching requirements, the rising projected cost of production, changing aviation mission of the Army (refusal to consider the changing threat environment), lack of sufficient funding for other critical aviation needs, the lack of achieving reduced risk of certain key technologies, and chronic groupthink.

Lakes Flying Company. The Lakes Flying Company was an early British aircraft manufacturer of seaplanes based at Windermere. In 1914 it was taken over by the Northern Aircraft Company Limited. 

A registered charity The Lakes Flying Company Ltd was established in 2010, "to celebrate and to inform the public concerning the importance of the innovative contributions made to the development of naval and civil marine aeroplanes by Captain Edward Wakefield and by Waterbird".

History
The first product of the Lakes Flying Company was the Lakes Water Bird, which first flew on 25 November 1911 but was destroyed in March 1912 when the Hangar collapsed in a gale. The Water Bird was the first successful British seaplane. It was followed by two further aircraft, the Water Hen and Sea Bird. The final design was the Hydro-monoplane. The seaplanes performed many pleasure flights from the Lake for the general public. In November 1914 the company was bought by the Northern Aircraft Company and the lakeside facility was expanded and pilot training (advertised as The Seaplane School) as well as pleasure flights were undertaken.

One of the pilots of the Northern Aircraft Company was John Lankester Parker, who became Chief Test Pilot for the Short Brothers company in Rochester, Kent and later Belfast, Northern Ireland.

Muhammad Arif Sarwari. Engineer Muhammad Arif Sarwari, also known simply as Engineer Arif, is a former Afghan intelligence official and politician.

Pre-Taliban
Sarwari studied electronics at a technical college, later transferring to Kabul Polytechnic. He did not complete his studies, instead joining the anti-Soviet resistance in 1982 during the Soviet–Afghan War. In 1992, after the ouster of the communists, he was appointed the chief of security of Kabul. He later served as the first deputy of National Directorate of Security. When the Taliban seized Kabul he joined the forces of Ahmad Shah Masoud, who was later to lead the Afghan Northern Alliance.

Northern Alliance and post-war
During the first Taliban rule, Sarwari was the chief intelligence official of the Northern Alliance under Ahmad Shah Massoud.
Massoud's September 9, 2001 assassination took place in Aref's office.

After the September 11 attacks, he was a major figure in coordinating with the CIA's Jawbreaker team, which worked with the Northern Alliance and prepared the way for further military operations. After the fall of Kabul, Sarwari and his organization took over the existing Afghan National Directorate of Security, but he was removed by Afghan President Hamid Karzai in early 2004 and replaced by Amrullah Saleh.

Governor of Panjshir
Sarwari was Governor of Panjshir Province .

Evacuation
After the Taliban captured Kabul in 2022, he was evacuated out of Afghanistan and into Kosovo.

Memorial to Heroes of the Marine Engine Room. The Memorial to Heroes of the Marine Engine Room is a granite monument located on St. Nicholas Place, at the Pier Head, in Liverpool, England.

History
The memorial was intended originally to commemorate all 32 engineers who died in the sinking of Titanic on 15 April 1912. Liverpool was the Titanic port of registry, as well as the home of the ship's owner, White Star Line. Construction was funded by international public subscription.

Spaces were left on the monument to record the names of other engineers. However, due to the heavy loss of life throughout World War I, its dedication was broadened to include all maritime engine room fatalities incurred during the performance of duty. Shrapnel damage from bombs that fell during the Blitz in World War II can be clearly seen on the monument.

Design

Standing  tall, the monument was designed by Sir William Goscombe John. It is constructed in the form of a granite obelisk standing on a square chamfered pedestal. The obelisk is topped with a gilded flame. Each of its bottom corners is decorated with carved representations of the four classical elements.

The east and west side of the pedestal feature carved life-size sculptures of stokers and engineers. Pevsner describes these figures as "strikingly naturalistic" and are noted as focusing on working class heroism. When the monument was designed, the use of manual labourers and workers was an uncommon subject in British public art and their inclusion by Goscombe John was considered innovative. Historic England describe the memorial as having a considerable influence on the future design of war memorials, calling it "one of the most artistically significant memorials to the Titanic disaster on either side of the Atlantic".

Double Eagle (mine disposal vehicle). The Double Eagle is a remotely operated vehicle (ROV) built by the Swedish defence company Saab Underwater Systems AB and used for the disposal of naval mines.

Design
As of 2009, four versions of the ROV have been designed.

The original version was named the Sea Eagle, and was a militarised variant of the civilian Sea Owl ROV. This unit was  long,  wide, and  high, could travel at , and dive to . These ROVs saw service with the Swedish Navy from 1984 onwards.

The second version, named the Double Eagle, is larger, measuring  in length,  in width, and  in height. The ROV weighs , can dive to , and travel at .

Current models
The Double Eagle Mark II is larger but lighter than the first Double Eagle. Measuring  long,  wide, and  high, the unit weighs , dives to , and can reach . The Mark II entered service in 1994.

The Mark III is  longer and  heavier than its predecessor.

The ROV's payload can consist of scanning sonar, echo locations, doppler logs, or self-navigation systems. All Double Eagles are equipped with an extendable manipulator arm, which is commonly used to place a small explosive charge on a mine. The ROV can be modified to double as a self-propelled variable depth sonar: the Mark II Double Eagles fitted to the French Navy's s have been altered to carry a Thales TSM 2022 sonar, while a similar upgrade is to occur to the Mark III units being acquired for the Tripartites of the Royal Netherlands Navy.

The Double Eagle Mark II uses two 5 kilowatt brushless electric motors for main propulsion, and six 0.4 kilowatt brushless electric motors for fine manoeuvering. Mark III ROVs have four 7 kilowatt brushless electric motors as main thrusters. Double Eagles can operate in any orientation.

Intermarine. Intermarine is an Italian shipbuilding company, owned by the Rodriquez Cantieri Navali Group.

Company
Founded in 1970, Intermarine specializes in building boats and ships with fibre-reinforced plastic hulls.

In September 2002, the company was acquired by Rodriquez Cantieri Navali, a builder of high-speed vessels. That led to Intermarine introducing ships which are built with steel and aluminum, using technology from its parent company. RCN owns four shipyards on the west coast of Italy and Intermarine has access to them for production. A shipyard was operated in the United States by the subcompany Intermarine USA after the purchase of the Sayler Marine Corporation shipyard in Savannah, Georgia in 1987; but with the 2002 acquisition by Rodriquez, that yard was no longer owned by the company.

As of December 2015, business mainly consists of the contract with the Italian Navy for a total of 176 million euros relating to the modernization of eight Gaeta-class minesweepers, and the contract with the Finnish Navy for the supply of three minesweepers and related logistic package, from the contract with Orizzonte Sistemi Navali for the supply of a navigating platform and a related logistic package.

Products
Intermarine builds exclusively military ships in three designs:  
Minesweepers are ships designed for the disposal of mines and for which Intermarine's composite construction is well suited, as the high elasticity of a composite hull makes it flexible enough to absorb the energy from a mine blast at close range without significant damage. Intermarine has built 38 minesweepers for seven customers, including three under construction for the Finnish Navy.
Intermarine built hydro-oceanographic catamarans for the Italian Navy; two were built for charting the seafloor.
Intermarine began producing patrol boats. Five patrol boats are under construction, but none have yet been delivered. They have either composite or aluminum hulls and are capable of speeds above 50 knots.

Slingsby Petrel. The Slingsby T.13 Petrel was a British single-seat competition glider built by Slingsby Sailplanes just before World War II.

Development

The Slingsby Petrel was a development of the German Schleicher Rhönadler designed by Hans Jacobs.  It was a single-seat high-performance sailplane with a span of a little under 18 metres, built of wood with a mixture of plywood and fabric covering. It had high cantilever gull wings, though the inner section dihedral was modest. They carried straight taper to fine and rounded tips and ailerons that extended over more than half the span. There were neither flaps nor airbrakes.

The fuselage had its maximum diameter near the nose, where the long, multipiece canopy blended in smoothly, ending at the wing leading edge.  Behind the wings the fuselage tapered and became slender at the tail.  The fin and the tailplane were both small in area; the rudder was large, aerodynamically balanced and extended down to the keel.  The elevators were tapered, with a cut out for rudder movement.  The undercarriage consisted of just a main skid from below the front of the cockpit glazing to mid chord plus a tail bumper.

Operational history

The Petrel prototype first flew in December 1938.  This aircraft crashed at Camphill, Derbyshire in the British National Championships of July 1939, killing its pilot, the speedway rider Frank Charles.  Two more were built and flew for several decades after World War II with clubs in England and Ireland.  One of them was a competitor at the 1953 British National Championships, held again at Camphill, by then known as Great Hucklow, after being bowled over in transit by a Rotherham trolley-bus.

Survivors

Only one Petrel, BGA651, the final aircraft, remains airworthy in 2013. It was restored by its owner, Graham Saw. It flies regularly at Vintage Glider Club meetings and has been displayed at Old Warden on Shuttleworth Collection open days.

The second Petrel, BGA418, has been restored back to its original varnished look.  It is flown at various glider meets throughout the U.S..  It can be seen on display, at the Western Antique Aeroplane and Automobile Museum (WAAAM) in Hood River, Oregon, United States.

NightMare. NightMare is a scareware program distributed on the Fish Disks for the Amiga computer (Fish #448). It is generally credited to be the first scareware program of its type.

The program was developed by Patrick Evans (Nobleton, Ontario, Canada) in 1990 and was free to redistribute, with source code available from the author.

Effects
When NightMare executes, it runs in the background. Every five minutes, it changes the entire screen of the computer for four fifths of a second to an image of a skull with blood on its teeth and a bullet hole with blood leaking out of it, and plays an echoing shriek on the audio channels.

Aeronor Flight 304. Aeronor Flight 304 was a Chilean domestic flight between the cities of Santiago and Antofagasta with two intermediate stops. On December 9, 1982, the Fairchild F-27 operating the flight crashed near La Florida Airport, in the Chilean city of La Serena. All 46 passengers and crew on board died.

Accident 
The Fairchild F-27 of Aeronor Chile was flying from Santiago to Antofagasta, with stops in La Serena and Copiapó.

The aircraft took off from Santiago at 09:40 (UTC−4), reaching the city of La Serena at 10:25. A few minutes before it was scheduled to land at La Florida Airport, the aircraft suffered a malfunction in one of its engines. After this, at 10:29, it crashed into a stone wall located in an area called "Parcela Seis" (Lot Six) at Alfalfares, located approximately 800 meters northeast of the airport terminal. After the aircraft crashed, it caught fire and was almost completely burnt. It is estimated that the aircraft crashed at a speed of 180 km/h. All forty-two passengers and four crew members were killed by the crash or subsequent fire.

Initially, the accident was mistaken for an emergency drill at the airport in La Serena which had commenced a few hours before the tragedy. A television crew from Canal 8 UCV TV, who were shooting scenes of the drill, managed to capture the Aeronor aircraft on fire shortly after the crash.

Cae Mabon. Cae Mabon is a retreat centre in North Wales, set in an oak forest close to the disused Dinorwic Quarry and on the opposite side of the Padarn lake from the town of Llanberis. 

The centre has been run by its founder, local storyteller, author, and songwriter Eric Maddern, since 1989 and is well regarded for the beauty of its natural setting as well as the architecture of its alternative, low-impact buildings.

In 2008, Cae Mabon was placed as the number one natural building project in the United Kingdom in the top ten list compiled by Professor Tom Woolley for sustain magazine. In the same year, the local authority granted retrospective planning permission on all the centre's alternatively constructed buildings, after support was shown for Cae Mabon by prominent local figures, including Dafydd Iwan. 

The name  means 'Field of Mabon' in Welsh, referring to Mabon ap Modron, a character from the Mabinogion.
