Foxjet ST600. The Foxjet ST600 was a small business jet under development in the United States in the late 1970s. Problems with development, particularly in finding a suitable powerplant, caused the project to be abandoned before any substantial work on the prototype had been done, but the concept proved to be ahead of its time, foreshadowing the very light jets of thirty years later.

Design and development
The ST600 was of familiar business jet configuration, with a low wing, cruciform tail, swept flying surfaces, and engines mounted on pods on the sides of the rear fuselage. The intentions of the project were to create a practical business jet small enough and light enough to take advantage of smaller airfields at a cost of around half of what full-size business jets of the day were selling for. Fuel costs were touted as being as low as nine cents a mile in 1977, compared to fifty cents a mile or higher for contemporary aircraft.

73 orders for the aircraft were taken with Bill Lear ordering the first example.

Three mockups were constructed and were widely displayed at aviation shows around the United States in the late 1970s by Tony Fox with slipping first flight schedules. The project got as far as Foxjet contracting Aeronca to construct the prototype. The engines, however, proved a major stumbling block. The tiny Williams Research type WR44 turbofan that had made the project possible received certification for use in a passenger-carrying aircraft, but due to its selection as the powerplant for cruise missiles, the United States government blocked non-military use of the engine. Without a suitable alternative available, the project could not proceed.

In 2006, a Foxjet mockup was exhibited at the AOPA expo at Palm Springs, Florida by Millennium Aerospace, which had purchased rights to the design in May. The company announced plans to resurrect the design and market it with Pratt & Whitney Canada PW615 engines.

The original prototype was eventually purchased by Lyle Anderson, of Princeton, Minnesota from a used motorcycle dealership in Minneapolis and prior to that, it stood in front of a car dealership. In 2010 it was put in Anderson's front yard, and was a participant in the Rum River Festival parade prior to relocation to Princeton Airport.

Frankfort Cinema. 

The Frankfort Cinema is a sailplane manufactured in the United States in the 1930s and 1940s and which was used by the United States Army Air Corps as a training glider under the designation TG-1. It was a high-wing, strut-braced design with a fully enclosed cabin. Originally designed as a single-seater, a two-seat version designated the Cinema II was produced soon afterwards, and this design was put forward when the Army issued a requirement for training gliders. At the same time, the company was awarded production contracts for transport gliders, the CG-1 and CG-2.

However, Frankfort lacked the resources to quickly produce large numbers of gliders, and only 43 TG-1s were delivered. The TG-1 designation was also applied to 10 civilian Cinemas that were impressed into Army service.

Molybdenum tetrachloride. Molybdenum tetrachloride is the inorganic compound with the empirical formula MoCl4.  The material exists as two polymorphs, both being dark-colored paramagnetic solids. These compounds are mainly of interest as precursors to other molybdenum complexes.

Structure
The α polymorph is a polymer. The β polymorph is a hexamer.  In both polymorph, the Mo center is octahedral with two terminal chloride ligands and four doubly bridging ligands.  In addition to these two binary phases, a number of adducts are know with the formula  where L is a Lewis base.

Preparation
α-Molybdenum tetrachloride can be prepared from by dechlorination of molybdenum pentachloride using tetrachloroethene:
 2MoCl5  +  C2Cl4   →  2MoCl4  +  C2Cl6

Heating α-molybdenum tetrachloride in a sealed container in the presence of molybdenum pentachloride induces conversion to the β polymorph.

Reactions
When heated in an open container, molybdenum tetrachloride evolves chlorine, giving molybdenum trichloride; 
 2MoCl4   →  2MoCl3  +  Cl2

The acetonitrile complex adduct can be prepared by reduction of the pentachloride with acetonitrile:
 2MoCl5  +  5CH3CN   →  2MoCl4(CH3CN)2  +  ClCH2CN  +  HCl
The MeCN ligands can be exchanged with other ligands:
 MoCl4(CH3CN)2  +  2THF   →  MoCl4(THF)2  +  2CH3CN

The pentachloride can be reduced to the ether complex MoCl4(Et2O)2 using tin powder. It is a beige, paramagnetic solid.

Thomas McMurtry. Thomas C. McMurtry (June 4, 1935 - January 3, 2015) was an American mechanical engineer, and a former naval aviator, test pilot at NASA's Flight Research Center and a consultant for Lockheed Corporation.

Early life and education
Born in Crawfordsville, Indiana, on 4 June 1935, McMurtry attended elementary school in Rockville, Indiana, and received his Bachelor of Science degree in mechanical engineering from the University of Notre Dame in June 1957.

Military career
A former U.S. Navy pilot and graduate of the United States Naval Test Pilot School, NAS Patuxent River, Maryland, McMurtry was a consultant for Lockheed Corporation before joining NASA in 1967.

NASA career
McMurtry joined NASA as a research test pilot in 1967. The first project he was assigned to as the project pilot was the F-8 Supercritical Wing project. He flew its first flight on 9 March 1971 and that of the NASA AD-1 on 21  December 1979. He was project pilot on the TF-8A Supercritical Wing testbed and the AD-1. He was co-project pilot on the F-8 Digital Fly-By-Wire Airplane, the 747 Shuttle Carrier Aircraft and performed digital electronic F-15 engine efficiency control tests. On 26 November 1975, the X-24B dropped from the sky for the last time, piloted on its 36th flight by McMurtry.

McMurtry co-piloted the 747 Carrier Aircraft as it transported the Space Shuttle Enterprise to its first launch on 12 August 1977. McMurtry logged over 11,000 hours of flying time since earning his pilot's wings in 1958. A graduate of the United States Naval Test Pilot School, he has flown many aircraft including the U-2, X-24B, F-8A, AD-1, YF-12C, F-104, and F-15. McMurtry became chief research test pilot and then Chief of the Research Aircraft Division for the NASA Ames-Dryden Flight Research Facility. He eventually rose to be the Director for Flight Operations at the NASA Dryden Flight Research Center, and retired on June 3, 1999, after 32 years of service and one day shy of his 64th birthday.

Retirement
Following his retirement from NASA, McMurtry flew his WACO open cockpit biplane and a Piper Cub.

Awards
McMurtry has been honored with the Society of Experimental Test Pilots' Iven C. Kincheloe Award for his work with the AD-1 Oblique Wing Airplane Program in 1982 and received Presidential recognition with the rank of Meritorious Executive in the Senior Executive Service. He was also awarded three NASA Exceptional Service Medals and the Aerospace Walk of Honor.

In 2012 McMurtry was nominated for an award by the Screen Actors Guild.
He was Wolfe Air's lead Vectorvision pilot.

In 2014 he accepted the Wright Brothers Master Pilot Award.

Reed Odourless Earth Closet. The Reed odourless earth closet (ROEC) is a variation on the ventilated improved pit (VIP) toilet where the pit is fully off-set from the Outhouse and is connected to the squatting plate by a curved chute.

The ROEC is fitted with a vent pipe to control odour and insect nuisance. It is claimed that the chute, in conjunction with the ventilation stack, encourages vigorous air circulation down the toilet, thereby removing odours and discouraging flies.

This type of latrine is common in southern Africa.

Design consideration for ROEC

Design life 
Most likely 4 to 15 years but the design life should be as long as possible: at least 10 years is desirable. The longer the design life, the longer the interval between relocating or emptying the latrine.

Dimensions 
Usually the pit cross-sectional area should not be more than 2 m2 in order to avoid cover spans with large spans. In practice, a ROEC serving one household commonly has a diameter of 1–1.5 m or in case of square or rectangular pits, a width of 1–1.5 m.

Vent pipe 
Vent pipe of a wide variety of materials are used, for example polyvinyl chloride (PVC), unplasticized PVC, bricks, etc. Whatever material is used, durability (including corrosion resistance), availability, cost and ease of construction are important factors. The vent pipe is sufficiently long such that the roof does not interfere with the action of wind across the top of the vent pipe. For both flat and sloped roofs, the top of the vent pipe should be at least 500 mm higher than highest point of the roof.

The internal diameter of the vent pipe depends on the required venting velocity necessary to achieve the recommended ventilation rate of at least 20 m3/h. This in turn depends on factors like internal surface roughness of the pipe, its length (which determines the friction losses), the head loss through the flyscreen and wind direction.

Flyscreen specification 
The purpose of the flyscreen is to prevent passage of flies and mosquitoes; therefore, the mesh is not larger than . The flyscreen is made of corrosion-resistant material that is able to withstand intense rainfall, high temperature and strong sunlight. Stainless steel screens are preferred.

Advantages 
As the pit is offset from the squatting hole excreta will not be seen, thus convenient to the users.

Parachlorobenzotrifluoride. Parachlorobenzotrifluoride is a synthetic halogenated organic chemical compound with the molecular formula . It is frequently abbreviated PCBTF. Parachlorobenzotrifluoride is a colorless liquid with a distinct aromatic odor. PCBTF has been commercially-produced since the 1960s, initially as an intermediate in the production of other petrochemicals. But since the 1990s, it has been primarily used as a solvent.

History
Occidental Chemical Corporation was a leading producer and sold it as part of its Oxsol® product line, specifically under the brand name of Oxsol 100. Occidental Chemical Corporation sold the OXSOL line to an Israeli company, Makhteshim Agan Industries, Ltd., in 2002.

Uses
PCBTF is increasingly used as a xylene replacement in cleaners, thinners, and other aromatic hydrocarbon blends.

PCBTF is used as a component (5-12%) of low volatile organic compound (VOC) compliant polyurethane finishes.  

The substance is used as an ink solvent in the printing industry. Parachlorobenzotrifluoride has a high capacity for dissolving many inks used by the printing industry. In most cases, up to 22 grams of ink can be dissolved in 20 grams of PCBTF. An added benefit is that parachlorobenzotrifluoride dissolves most inks faster than toluene.

Health and Environmental effects
Health effects:
 Points of entry: eyes, ingestion, inhalation, skin.
 Target organs: central nervous system, kidneys, liver.
 Irritancy: eyes, respiratory tract, skin

In the troposphere, PCBTF has an estimated half-life of 67 days. It is transformed by reaction with photochemically-produced hydroxyl radicals to give mainly 2-chloro-5-trifluoromethylphenol.

Regulation
PCBTF currently has VOC Exempt status from the U.S. Environmental Protection Agency. However, California's Office of Environmental Health Hazard Assessment (OEHHA) has adopted inhalation risk factors for PCBTF as of June 2019, which could have implications for its ongoing VOC Exempt status.

I-670 Viaduct. 

History and Significance
Named after Jay B. Dillingham, a prominent figure in the history of the Kansas City Stockyards, the viaduct serves as a critical link within the regional transportation network, easing the flow of intercity and interstate traffic. Its strategic location—nestled between the Missouri Pacific Bridge to the north and the Central Avenue Bridge (Kansas City) to the south—underscores its importance in connecting key urban areas across the Kansas River.

Design and Construction
The bridge features a multi-beam girder design, chosen for its strength and ability to support the significant volume of traffic characteristic of a major interstate route. Its construction in 1990 was part of a larger effort to improve connectivity and foster economic growth within the Kansas City area. The completion of the I-670 Viaduct represented a notable advancement in the region's infrastructure development.

Impact and Usage
As a vital component of the Interstate 670 corridor, the viaduct plays a key role in facilitating daily commutes and the transport of goods and services between Kansas and Missouri. The proximity of the bridge to important landmarks and economic centers, including the West Bottoms district, amplifies its significance in the local infrastructure network.

Hexafluoropropylene oxide. Hexafluoropropylene oxide (HFPO) is an intermediate used in industrial organofluorine chemistry; specifically it is a monomer for fluoropolymers.  This colourless gas is the epoxide of hexafluoropropylene, which is a fluorinated analog of propylene oxide, HFPO is produced by Chemours and 3M and as a precursor to the lubricant Krytox and related materials.  It is generated by oxidation of perfluoropropylene, e.g. with oxygen as well as other oxidants.

Reactivity
Fluoride catalyzes the formation of perfluorinated polyethers such as Krytox.  The initial step entails nucleophilic attack at the middle carbon to give the perfluoropropoxide anion, which in turn attacks another monomer.  This process generates a polymer terminated by an acyl fluoride, which is hydrolyzed to the carboxylic acid which is decarboxylated with fluorine. The net polymerization reaction can be represented as:
n +2 CF3CFCF2O  →  CF3CF2CF2O(CF(CF3)CF2O)nCF2CF3  +  CO

Upon heating above 150 °C, HFPO decomposes to trifluoroacetyl fluoride and difluorocarbene:
CF3CFCF2O   →  CF3C(O)F  +  CF2
The epoxide of tetrafluoroethylene is even more unstable with respect to trifluoroacetyl fluoride.

In the presence of Lewis acids the compound rearranges to hexafluoroacetone, another important chemical intermediate. This rearrangement can be of concern during storage as the rearrangement be catalyzed by the material of the storage cylinder's walls and leads to unwanted formation of HFA during storage. As a result of this, 3M recommends using all HFPO shipped in carbon-steel containers within 90 days of shipping.

Methanolysis affords methyl trifluoropyruvate, a reagent useful in organic synthesis:
CF3CFCF2O  +  2 MeOH →  CF3C(O)CO2Me  +  MeF  +  2 HF
