Ralph Freeman (civil engineer, born 1911). Sir Ralph Freeman CVO CBE (3 February 1911 – 24 August 1998) was an English civil engineer, responsible for the design of the Humber Suspension Bridge - the longest in the world until 1998. He was the son of Sir Ralph Freeman, designer of the Sydney Harbour Bridge.

He was educated at Uppingham School, Rutland and Worcester College, Oxford. Sir Ralph worked on bridges in South Africa and Rhodesia, where he met his wife Joan Rose, before returning to England in 1939 and joining Freeman Fox & Partners, a firm of consulting engineers (called Douglas Fox & Partners before changing its name in 1938 in honour of Sir Ralph's father, a senior partner there).

Freeman served in the Royal Engineers during the Second World War as a Captain in the Experimental Bridging Establishment in Christchurch, Hampshire, England. He was involved in the development of a propped military suspension bridge. Freeman served in the volunteer Engineer and Railway Staff Corps, providing engineering expertise to the army, and was gazetted at the rank of Major in that corps on 6 October 1953.

He then returned to Freeman Fox & Partners, eventually retiring in 1979, having worked on a variety of large projects: the M2 and M5 motorways, the Forth Road Bridge, the Severn Bridge, both Bosporus bridges, and the harbour tunnel and mass transit rail systems in Hong Kong. He served as president of the Institution of Civil Engineers in 1966–7.

The pinnacle of his career was the Humber suspension bridge which, when it opened in 1981, was the longest single-span suspension bridge in the world, 1410m between its two 155m-high pylons.

His son, Ralph (but known as Anthony), who also took up civil engineering, died in July 1998 after an accident on the Vasco da Gama bridge in Lisbon.

Avia BH-8. 
The Avia BH-8 was a prototype fighter aircraft built in Czechoslovakia in 1923. It was an unequal-span biplane developed on the basis of the ill-fated BH-6 design, in an attempt to address that type's problems. It shared the BH-6's unusual wing cellule design.

When test-flown in late 1923, it did indeed display better flying characteristics than its predecessor, but was overtaken in development by another variation of the same design, the BH-17.

Huff-Daland TA-2. The Huff-Daland TA-2 was an American biplane trainer designed by the Huff-Daland Aero Corporation in the early 1920s for the United States Army Air Service.

Design and development
The TA-2 was a development of the Huff-Daland HD.4 Bridget with a  ABC Wasp radial engine. Three prototypes (one for static tests and two fliers) were ordered for evaluation at McCook Field. The two flying examples were later rebuilt with a re-designed fuselage, balanced rudder, smaller wings and a  Curtiss OX-5 engine. One aircraft was later re-engined with a Lawrance J-1 radial engine.

The TA-2 was re-designed with a  Lawrance J-1 engine and re-designated the Huff-Daland AT-6, one prototype only was built.

Amtrak Arrow Reservation System. Amtrak's Arrow Reservation System is used nationally in the United States by Amtrak employees to take reservations, check train status, and monitor Amtrak equipment throughout the  of the Amtrak network. Arrow was created to make Amtrak's reservation taking more simple. It went online November 1, 1981. Arrow development is done in-house by Amtrak developers. 

The Arrow application is similar to most major airline reservation systems, and runs on IBM's Transaction Processing Facility system.  The system is used directly by Amtrak employees and travel agents, and is also the basis for Amtrak.com and Quik-Trak reservations.

On August 26, 2007, the system was the victim of a major power outage at the data center, which impacted Amtrak nationwide. All Amtrak agents were forced to hand-write tickets, and were unable to use the system for any other purposes.

In 2015 a project to upgrade Amtrak's reservation infrastructure left the future of Arrow uncertain with a decision to upgrade or replace it unmade.

LuAZ-967. The LuAZ-967 () was the Transporter of the Front Line, a small Soviet four-wheel drive amphibious vehicle. Light enough to be air transportable, it had a  payload over most terrain.

History
The design originated after the Korean War, when the Soviets saw a need for small off-road vehicles comparable to the American Jeep, to supplement the overly-large and -heavy GAZ-69s then in service. It was to be used by Soviet Airborne Forces (VDV) for casualty evacuation, munition supply and the transport of light armaments.

Developed at NAMI (the National Automobile Institute), the prototype, known as NAMI 049, was completed in 1958. Unlike the Jeep, it had a Fibreglass body, four-wheel torsion bar independent suspension, and permanent four-wheel drive with locking hubs. It had a wheelbase of , a ground clearance of , and was powered by a  MD-65 motorcycle engine (copied from an Orbita motorcycle). Trials proved it underpowered, and the body too fragile.

A second prototype, the NAMI 049A, had a  V4 MeMZ-965 engine (selected for use in the ZAZ-965), steel body, and rear wheel drive (with optional drive to the front wheels). The torsion bars were replaced with a coil spring setup. It weighed , with a  MeMZ-967A engine, and was able to pull a  trailer; it could cross a 58° gradient, and top speed was .

It was produced between 1961–1975 at Lutsk automobile plant - LuAZ. It was succeeded by the LuAZ-969В, LuAZ-969, LuAZ-969М and the LuAZ-1302.

Modifications
 LuAZ-967A — modernized high-powered engine MeMZ-967А
 LuAZ-967M — modernized ЛуАЗ-967А with the same engine.
 Geolog - a specialized 6-wheel version.

Mechanical
The LuAZ-967M had a MeMZ-967A  gasoline engine from the ZAZ automobile. An air-cooled, carbureted ohv V4, it developed  at 2,250 rpm.

A 4+1 speed transmission has separately engaged crawl gear. Unlike many small military vehicles, it was a front wheel drive 4×2, the rear axle was selectively engaged only when 4×4 was needed.

The watertight steel body had 4-wheel independent suspension with torsion bars and  of ground clearance. The driving controls were on the truck's centerline, both the controls and the windshield could be folded down for a lower profile.

ETS-VIII. JAXA Engineering Test Satellite ETS-VIII (Kiku 8) was the eighth technology test satellite in a series which started with ETS-1 in 1975 by NASDA. It was launched with the H-2A on December 18, 2006. ETS-VIII was developed by JAXA in cooperation with NICT and NTT. The aim of ETS-VIII was to enable satellite communications with small terminals. Unlike the Iridium satellites for mobile communication, ETS-VIII was positioned at GEO.
However to fulfill the task, it was essential that the satellite carried two very large antennas. It was the first use of the 204 configuration (four strap-on boosters) of the H-IIA launch vehicle.

Timetable
December 20, 2000: Launch of LDREX, a demonstration of the large antenna reflector deployment, aboard Ariane 5.  Deployment failed.
October 14, 2006: Launch of LDREX-2 with the Ariane 5, model antenna deployed successfully.
December 18, 2006: ETS-VIII was launched aboard H-IIA.
December 26, 2006: Both antennas were deployed. 
January 9, 2007: GEO orbit injection.    
May 9, 2007: The satellite switched to normal operation phase. 
January 10, 2017: Decommissioned.

Cisco TelePresence. Cisco TelePresence, first introduced in October 2006, is a range of products developed by Cisco Systems designed to link two physically separated rooms so they resemble a single conference room, regardless of location.

Cisco documented the Telepresence concept and implementation details in the book Cisco TelePresence Fundamentals, where the difference between Telepresence and Videoconferencing, prevalent at that point in time, is defined as quality, simplicity, and reliability.

Products 
These were the initial products:

CTS-3000 - Room system for 6 persons
CTS-1000 - Room system for 2 persons
CTMS - Multipoint collaboration network appliance that connected multiple room systems into a single conference
CTS-Man - Management application for integration with groupware, such as Microsoft Exchange which gives the system the ability to schedule meetings

They were designed so that the experience was as if local and remote participants were in the same room. These products offer features including up to three 1080p flat panel displays, special tables, microphones, speakers, cameras, collaboration interfaces and lighting.

In 2008 Cisco reported to have sold about 2,000 rooms, with about another 250 non-revenue (internal and philanthropic) units installed.

Later, other products were developed that expanded the use-cases for smaller offices and Webex connectivity.

In 2010 Cisco acquired the Norwegian company Tandberg and integrated their products into the Cisco portfolio.

Currently, a wide range of collaboration endpoints  and conferencing infrastructure products  is offered.

Marketing
The television series 24 featured Cisco Telepresence product placements.
Season 8. Episode 8 of NCIS also featured Cisco Telepresence product placements.
The Video Game Tom Clancy’s Splinter Cell: Conviction (2010) featured Cisco Telepresence product placements.

Airbridge (logistics). An airbridge is the route and means of delivering material from one place to another by an airlift.

An airbridge is the means by which an airhead is kept supplied by flying over enemy held territory. An airlift over an airbridge can also be used when the most convenient means of transport is by air, or as an additional supplement to other forms of transport. 

During the Second World War, the Germans used air bridges on three major occasions: the Demyansk Pocket, the Battle of Stalingrad and the Kuban bridgehead. As Demyansk turned into a German victory with the success of the bridge, Hermann Göring convinced Hitler a similar method could be used to supply the Sixth Army at Stalingrad. However, the Luftwaffe was never able to send in the necessary 800 tons of supplies per day. The Kuban Airlift from February–March 1943 was much more successful as the German air units in the Taman peninsula had access to established airfields with good supply and maintenance facilities, the weather was more favorable and Soviet opposition was much weaker than at Stalingrad. In February 1943, the Germans evacuated 50,000 men by air from the northwestern Caucasus to the Crimea and Ukraine. German units within the Kuban bridgehead received by air a daily ration of 500 tons of ammunition, food, fuel and other supplies, which would have been enough to keep 6th Army in Stalingrad operational. Some 2,000 men were airlifted every day from the Kuban bridgehead. At maximum effort, the Caucasus airlift brought in 700 tons of supplies and evacuated 5,000 men on a daily basis. 

During Croatian War of Independence and Bosnian War, Croatian government supplied Bosnian 5th Corps in Bihać enclave surrounded by Serb forces. The Fifth Corps was supplied by materiel using Mi-8/17 helicopters and smaller airplanes. The missions were flown by foreign mercenary pilots from Ukraine, Russia and Hungary for a fee of 5000 Deutsche Marks per flight as these missions were considered very dangerous. Out of 101 organized flights, 91 were successful and 10 failed.

Two of the largest airbridges in history were: The Hump, (the name given by Allied pilots in the Second World War to the eastern end of the Himalayan Mountains over which they flew from India to China to resupply the Chinese Government forces of Chiang Kai-shek) and the US XX Bomber Command (during Operation Matterhorn);  and the Berlin Airlift, to overcome the Berlin Blockade from 24 June 1948 through to 11 May 1949.

Following the 1982 Falklands War, the United Kingdom established the Falklands Airbridge (also known as the RAF Airbridge or South Atlantic Airbridge) between RAF Brize Norton in the UK and RAF Mount Pleasant in the Falkland Islands (via RAF Ascension Island). The service facilitates both civilian and tourist air connectivity and reinforces the British Forces South Atlantic Islands garrison.

Luthite. Luthite is a lightweight synthetic material developed by the Westheimer Corporation (a United States-based importer of Cort Guitars) for the construction of bass guitar and electric guitar bodies. The 1996 patent application credits Jack L. Westheimer as the sole inventor. The term refers both to the composite material and to its forming process. Luthite is very similar in purpose to the later Vibracell used in the all-plastic Switch Music instruments.

Luthite was developed specifically for use in building stringed musical instruments (luthiery). The intention was to create a substitute for wood in building solid-body electric guitars and basses, as there is much greater control over the consistency of production, and thus of tone and overall quality from one instrument to the next. Additionally, the material is able to be formed to almost any shape (i.e. 3-D shapes out of plane) where the wood equivalent would require a very large body blank or laminates.

Apart from these advantages, Luthite is less resistant to impact than its wooden counterparts, which renders finished instruments more susceptible to dings and chips; or developing cracks if dropped or otherwise stressed. 

Luthite was employed in Ibanez  Ergodyne series electric guitars (EDR/EXR) and basses (EDA/EDB/EDC), and Cort Curbow series basses.

Air Staff (United Kingdom). Air Staff is the body of Royal Air Force officers responsible for the running of the RAF. Generally, the heads of the various departments of the Air Staff formed, together with members of the Air Ministry (the British government department in charge of aviation matters), the Air Council. 

The Air Staff issued "Targets" (AST) which were a stated requirement for an aircraft to fulfil a role within the RAF. E.g Air Staff Target 362 was for a trainer aircraft to replace the Folland Gnat, the resulting aircraft was the SEPECAT Jaguar. When a specification moved from the initial requirements to a production contract, it became an Air Staff Requirement (ASR).

Composition
The Air Staff was composed of several posts.

Chief of the Air Staff
Deputy Chief of the Air Staff (1918-1968/9)
Assistant Chief of the Air Staff - replaced Vice Chief and two Assistant Chief posts
Vice Chief of the Air Staff (1940-1985)
