Breda Ba.88
The Breda Ba.88 Lince (Italian: Lynx) was a ground-attack aircraft used by the Italian Regia Aeronautica during World War II. Its streamlined design and retractable undercarriage were advanced for the time, and after its debut in 1937 the aircraft established several world speed records. However, when military equipment was installed on production examples, problems of instability developed and the aeroplane's general performance deteriorated. Eventually its operational career was cut short, and the remaining Ba.88 airframes were used as fixed installations on airfields to mislead enemy reconnaissance. It represented, perhaps, the most remarkable failure of any operational aircraft to see service in World War II.

Geotechnical Investigation
Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil and rock around a site to design earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions. This type of investigation is called a site investigation. Additionally, geotechnical investigations are also used to measure the thermal resistivity of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities. A geotechnical investigation will include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved. Surface exploration can include geologic mapping, geophysical methods, and photogrammetry, or it can be as simple as a geotechnical professional walking around on the site to observe the physical conditions at the site. To obtain information about the soil conditions below the surface, some form of subsurface exploration is required. Methods of observing the soils below the surface, obtaining samples, and determining physical properties of the soils and rocks include test pits, trenching (particularly for locating faults and slide planes), boring, and in situ tests.

FYFT P-Series Unmanned Blimp
FYFT P-series unmanned blimps are Chinese UAVs developed by Qingdao Co., Ltd. Fei-Yu (meaning Flying Universe) Aviation Science and Technology Co., Ltd. (FYFT, 青岛飞宇有限公司), and these unmanned blimps are named after their respective length. For example: if an A1 series blimp is 11 meter long, then it is named A1-1100, because 11 meter is equal to 1100 millimeter. P-series unmanned blimps are intend for law enforcement applications, and P stands for Police. The greatest difference between P-series and other unmanned blimps for civilian use such as S-series unmanned blimps for aerial survey is that for law enforcement application, data link is added to provide real-time or near real-time transmission of information gathered so police can respond in a timely manner, as opposed to civilian versions where information is downloaded and evaluated after the UAVs have landed.

Socio-Economic Aspects of Sustainable Mobility
The importance of transportation in terms of economic growth and human resources cannot be overstated. The way people move to work or enjoy recreation, how companies send workers to reach clients, and how businesses ship goods to distribution centres—transport shapes lives and underpins everything. The goal of the transportation system should be to advance the excellence of life in the city and suburbs by providing a safe, dependable, integrated, multi-modal, effective, and environmentally friendly transportation system (particularly by employing low/zero-emission cars, park and ride solutions, and so on). There are various socioeconomic facets of sustainable mobility. In addition, some of them also overlap with the environmental or technical categories.

Skiffing
Skiffing refers to the sporting and leisure activity of rowing (or more correctly sculling) a Thames skiff. The skiff is a traditional hand built clinker-built wooden craft of a design which has been seen on the River Thames and other waterways in England and other countries since the 19th century. Sculling is the act of propelling the boat with a pair of oars (or blades), as opposed to rowing which requires both hands on a single oar.

Electric Vehicles with Vehicle-to-Grid Capability
Electric vehicles (EVs) with vehicle-to-grid (V2G) capability can serve various applications that are being investigated in literature and tested in the field. EVs can participate in existing markets via V2G technology such as energy trading (i.e., spot markets) and frequency control. Furthermore, V2G capability can be utilized to execute behind-the-meter energy flow optimization such as load leveling and peak shaving. Heiltmann and Friedl review factors influencing the economic success of vehicle-to-grid applications in market and behind-the-meter use cases. They find that load leveling and secondary frequency control provide the highest economic benefits for PHEV controlled charging applications. Furthermore, DSO services such as congestion management, power loss minimization, power quality improvement and voltage regulation are topics of investigation for EV participation utilizing V2G technology.

AFVG
AFVG (standing for Anglo-French Variable Geometry) was a 1960s project for supersonic multi-role combat aircraft with a variable-geometry wing,[N 1] jointly developed by British Aircraft Corporation in the United Kingdom and Dassault Aviation of France. The project was borne out of ambitions to produce a viable combat aircraft that made use of the variable-sweep wing, as well as to promote wider cooperative efforts between France and the United Kingdom. However, neither Dassault not the French Air Force were particularly keen on the AFVG; the project was further impacted by repeated specification changes and indecision for what roles that the AFVG was to be tasked with on the part of Britain. In mid-1967, British requirements settled upon adopting the AFVG for the Royal Air Force (RAF) for the strike role in the place of the cancelled BAC TSR-2 strike bomber. The project was cancelled in June 1967, when the French Government withdrew from participation. However, the cancellation was not the end of work on the proposed design. BAC modified the specification to solely satisfy Royal Air Force (RAF) needs, reconfiguring the design as the UKVG and sought out new partners to procure the aircraft, which ultimately emerged as the Anglo-German-Italian consortium-funded MRCA (Panavia Tornado), a variable-geometry wing fighter/strike aircraft.

Growler (Vehicle)
The M1161 Growler is officially the Internally Transportable Light Strike Vehicle (ITV-LSV) designed specifically for use with the V-22 Osprey tiltrotor aircraft. The M1161 and M1163 are the only tactical vehicles certified to fly in the V-22. Fulfilling multiple roles of light utility, light strike and fast attack vehicle, the M1161 Growler is smaller than most international vehicles in the same role. It has taken over duties of the M151 jeep-type variants and replaced the Interim Fast Attack Vehicle (IFAV). A separate US Marine Corps variant, the shorter two-seat M1163 prime mover is combined with the M327 towed 120mm heavy mortar, and also became its ammunition hauler after the M1162 trailer was cancelled.

BFR Tanker
The Big Falcon Rocket (officially shortened to BFR) is a privately funded fully reusable launch vehicle and spacecraft system in development by SpaceX. The overall space vehicle architecture includes both launch vehicles and spacecraft, as well as ground infrastructure for rapid launch and relaunch, and zero-gravity propellant transfer technology to be deployed in low Earth orbit (LEO). The payload capacity to Earth orbit of at least 100,000 kg (220,000 lb) makes BFR a super heavy-lift launch vehicle. The first orbital flight is tentatively planned for 2020. SpaceX has been developing a super heavy-lift launch vehicle for many years, with the exact design and nomenclature of the vehicle undergoing multiple revisions over time. Before 2016, the vehicle was referred to as the Mars Colonial Transporter (MCT), though very few details about the design of the MCT were ever made public. Starting from 2016, SpaceX began sharing annual updates with the public, detailing the designs and uses of their upcoming new launch vehicle. In 2016, SpaceX CEO Elon Musk presented the vehicle at the International Astronautical Congress as the ITS launch vehicle, forming a core part of Musk's comprehensive vision for an Interplanetary Transport System (ITS). The ITS vehicle had a 12-meter (39 ft) core diameter, but was only intended for interplanetary travel. In September 2017, the design (now known as the BFR) was scaled down to 9 meters (30 ft) While the ITS had been solely aimed at Mars transit and other interplanetary uses, SpaceX pivoted to a plan that would support all SpaceX launch service provider capabilities with a single set of 9-meter vehicles: Earth orbit, lunar orbit, Interplanetary spaceflight, and potentially, even intercontinental passenger transport on Earth. In September 2018, a redesign of the second stage was announced, adding steerable canards, two radially adjustable fins also acting as landing legs, and a third leg that looks like a vertical stabilizer but has no aerodynamic function due to the special re-entry profile of the spacecraft. The launch vehicle design is dependent on the concurrent development work on the Raptor rocket engines, which are cryogenic methalox-fueled engines to be used for both stages of the BFR launch vehicle. Development on the Raptor began in 2012, leading to engine testing which began in 2016. The BFR system is intended to completely replace all of SpaceX's existing space hardware (the Falcon 9 and Falcon Heavy launch vehicles, and the Dragon spacecraft), initially aiming at the Earth-orbit launch market, but explicitly adding substantial capability to support long-duration spaceflight in the cislunar and Mars transport flight environments.
