Blackburn H.S.T.10. The Blackburn H.S.T.10 (sometimes known as the Blackburn B-9) was a 1930s British twin-engined commercial monoplane, designed and built by Blackburn Aircraft at Brough, East Yorkshire.

Design and development
The H.S.T.10 was a low-wing cantilever monoplane powered by two Napier Rapier VI engines. It had a retractable conventional landing gear with an enclosed cabin for two pilots and twelve passengers. It was fitted with a single-spar all-metal wing. The single tubular spar, known as the Blackburn-Duncanson, had previously been tested on a Blackburn Segrave. Claimed to be lighter than a two spar design while also stiff in "torsion and bending", the spar also served as the fuel tank. 

Intended to be "high speed" by careful attention to shape and removing "protuberances" with retractable undercarriage, the expected performance was 320 miles with two pilots and twelve passengers which increased to 1000 miles with both pilots and five passengers.

The pilots had individual rudder pedals but a single "handle" on the central control column which could be swung in front of either pilot seat. The cockpit was separated from the  by  by  high cabin. At the rear of the aircraft was a toilet and a  luggage space. Configurations drawn up by Blackburn included 12- and 8-seat passenger cabins or 4 bunks/stretchers as a medical transport.

The prototype used test serial B-9. In 1937, the project was abandoned, and B-9 was given to Loughborough College as an instructional airframe.

Laister LP-49. The Laister LP-46 and LP-49 are a family of American high-wing, single-seat, gliders that were designed by Jack Laister and produced by Laister Sailplanes both as kit aircraft and as certified complete aircraft.

Design and development
The original model, the LP-46 was first flown in 1966, with the LP designating Laister Products. The LP-46 features a  wingspan and the first LP-46 has fixed monowheel landing gear.

The LP-49 is an improved version of the LP-46, designed for the Standard Class with a  wingspan. The LP-49 has a metal wing with a NACA 64(3)-618 laminar flow airfoil and all-metal tail surfaces. The control surfaces are all counter-weighted with internal weights. The fuselage is a semi-monocoque fiberglass design, mounting a shock-strut suspended retractable monowheel landing gear with an automatic swivelling and retractable tailwheel. The ailerons and dive brakes automatically hook up on aircraft assembly. Due to the fuselage construction the aircraft type certificate contains the restriction "All external portions of the fuselage exposed to sunlight must be painted white, except for a minimum amount of light shaded markings."

The LP-49 was static-tested to 12 g and is approved for aerobatics including loops, spins and wing-overs. The aircraft is often called The Forty-Niner.

Operational history
In March 2011, there were two of the three LP-46s built registered with the Federal Aviation Administration in the US, all certified aircraft. Also in March 2011, there were 24 LP-49s registered. Of the registered LP-49s 17 are certified and seven are amateur-built.

Schmitz Park Bridge. The Schmitz Park Bridge is a  concrete-box bridge that spans a ravine in Seattle's Schmitz Park. Built in 1936, the structure is both listed in the National Register of Historic Places and is a designated city landmark.

The bridge was designed by city engineer Clark Eldridge. It replaced a timber-truss span that had been erected in 1916. The funds were provided by the federal Public Works Administration and by local gas-tax and highway funds. The rigid frame created by the concrete box cells made the structure 60 percent longer than any such bridge previously constructed.

The graffiti artwork underneath the bridge has received praise in C-Monster's art blog and from a critic with the Seattle Post-Intelligencer.

Severinghaus electrode. The Severinghaus electrode is an electrode that measures carbon dioxide (CO2). It was developed by Dr. John W. Severinghaus and his technician A. Freeman Bradley in 1958.

It utilizes a CO2-sensitive glass electrode in a surrounding film of bicarbonate solution covered by a thin plastic carbon dioxide permeable membrane, but impermeable to water and electrolytic solutes. The carbon dioxide pressure of a sample gas or liquid equilibrates through the membrane and the glass electrode measures the resulting pH of the bicarbonate solution.

Clark, galvanic, and paramagnetic electrodes measure oxygen.  Severinghaus electrode measures .  Sanz electrode measures pH.

Sam White Bridge. The Sam White Bridge is a reinforced concrete and steel overpass beam bridge which crosses Interstate 15 in American Fork, Utah. The original bridge was named for Sam White, a former homesteader in the nearby city of Pleasant Grove. It had only  underpass clearance. The new bridge has an underpass clearance of , which exceeds the minimum standard for interstate bridges in the United States.

The new 354-foot, 3.82-million-pound (1.73-million-kg, 1910-short-ton, 1733-tonne) bridge was built on the side of the interstate— from its final location—in order to reduce traffic impact. It was then moved into place over a five-hour period using self-propelled modular transporters, finishing the process three hours ahead of schedule.  It is the longest two-span bridge to be moved in the Western Hemisphere, and the second longest in the world to be moved.

The Utah Department of Transportation, state and federal transportation and construction officials from around the United States, as well as some from other countries, were present to view it being moved into place. An area of a nearby business park was set aside for the public to watch the bridge being moved into place.

Lisa Hammond (potter). Lisa Hammond (born 1956) is a British studio potter.

Life and Practice 
She is a Fellow of the Craft Potters Association of Britain.  She has specialised in vapour glazing since leaving college, first using salt and, since the early 1980s, soda glaze.  She produces a range of functional ware for the preparation, cooking and serving of food.  Alongside functional ware, she makes a range of work that she describes as "individual and playful". Hammond worked in Greenwich, London from 1979 and briefly set up a studio in Okehampton, Devon. In 2003-2004, she spent three months making and firing in the Mino, Gifu, area for several exhibitions in Japan. She taught ceramics at Goldsmiths College, London, and has lectured and exhibited widely. In 2012 Hammond relocated back to Greenwich, London, to Maze Hill Pottery. Over the course of her career she has taught upwards of a dozen apprentices at both Maze Hill Pottery and Kigbeare Pottery for periods ranging from one to three years, notable apprentices includes Yo Thom, Adam Frew, Billy Lloyd, Yoji Yamada, Darren Ellis, Florian Gadsby, Dom Upson and Francis Lloyd-Jones. Hammond has been described as one of the most committed and driven of modern studio potters, "one of a small number who have clearly inherited the mantle of studio pioneers like Michael Cardew" and "the best woman potter working in Britain." Her work is represented in museums and collections in the UK and abroad.

Clay College 
In 2017  Hammond founded Clay College Stoke, based in Middleport Pottery, a skills-based, full-time ceramics course taught by potters from throughout the country and internationally. Set up costs for the college were successfully crowdfunded initially and it was officially opened by Charles, Prince of Wales, whose charity, the United Kingdom Historic Building Preservation Trust, funded £9 million to restore the historic factory.

Awards 
Hammond was awarded an MBE in the 2016 birthday honours list.

Laister LP-15 Nugget. The Laister LP-15 Nugget is an American single-seat, high-wing glider designed by Jack and Bill Laister for the FAI Standard Class. It first flew in 1971.

Design and development
Designed in the 1970s, the Nugget was intended to compete with the new European fiberglass gliders that were beginning to appear, and as such incorporated mixed construction methods. The fuselage is built with a fiberglass cockpit area, with the fuselage aft of the wing trailing edge made from aluminum. The wing is of Chem-weld bonded aluminum construction, the bonding replacing rivets in an attempt to get a surface as smooth and wave-free as fiberglass. The wing employs a Wortmann FX 67 170/150 airfoil and has flaps. The long span flaps serve both as speed-range drag reducing camber changing devices and full deflection high-lift/high-drag landing flaps. The aircraft can carry up to  of water ballast in a center fuselage tank, located at the center of gravity. The landing gear is a retractible monowheel.

Even though several sources report that the LP-15 was type certified, no type certificate was ever filed for it and all aircraft are registered as Experimental-Racing, Experimental-Exhibition or Experimental-Amateur-built. The LP in the designation indicates Laister Products and the model number is the wingspan in metres.

Operational history
As of January 2016 there were still 9 LP-15 Nuggets registered in the USA.

AAI Sparrowhawk. The AAI SparrowHawk is an American two-seat pusher ultralight autogyro, available in kit form for amateur construction.

Design and development
AAI (American Autogyros Inc) was formed as a division of Groen Brothers Aviation (GBA) late in 2002, with the initial task of improving stability in existing autogyros.  After a series of such modifications they decided to develop their own aircraft and a proof-of-concept machine first flew in February 2003.  This was based around the pod of an RAF 2000 autogyro but had a different tail design.  The first AAI built production prototype flew on 25 February 2004.

The SparrowHawk is a pusher configuration autogyro with an uncowled single 160 hp (120 kW) Subaru EJ25 flat-four engine mounted behind a totally enclosed glass fibre cabin.  This pod, which seats two side by side, has almost triangular sides and is entered via optional large, partially glazed doors. An aluminum keel projects aft of the pod and a vertical member fixed to it carries the engine and rotor mast.  The two-bladed rotor is of bonded metal construction.

The tail unit is attached by a pair of aluminum centreline booms.  The upper one is mounted directly on the vertical engine/rotor mast and is cranked near midpoint to clear the propeller tips.  The lower one is attached well below the keel on an extension plate. They support a deep, wide chord, finless rudder, formed from honeycomb composites material and carrying a pair of fixed horizontal stabilizers with small endplate fins. The rudder has self-centring springs. The resulting cruciform structure is centred on the propeller thrust line for dynamical stability.

The SparrowHawk has a tricycle undercarriage with three equal-size wheels mounted off the keel, supplemented by a smaller tailwheel.  Steering on the ground is by rudder pedal-controlled differential braking and a steerable nosewheel.

Operational history
The first kit built SparrowHawk flew in Russia on 23 September 2004. Dealerships were established in North, Central and South America, in India, East Asia and South America. 125 kits had been sold by mid-2008.  By November 2009 there were 45 SparrowHawks on the US civil register.  One SparrowHawk was on the European (west of Russia) registers in mid-2010. The Russian version is marketed by Aro-Avia.

In 2008 GBA announced its intention to sell off the SparrowHawk program. A press release in January 2011 announced an agreement with Guangzhou Suntrans Aviation Science and Technology Co., Ltd. to form a Cooperative Joint Venture for the manufacture of SparrowHawks in China.
