Stollergrund-class multi-purpose ship. The Type 745 Stollergrund-class multi-purpose ship was a class of multi-purpose ships built for the Wehrtechnische Dienststelle 71 (WTD 71) of the German Navy in Eckernförde and the Marinearsenal Wilhelmshaven. Three units are still in use for the WTD 71, the other two boats were sold to the Israeli Navy.

Development 
As a replacement for older test and support vehicles, five small test boats (designation according to the list of ship numbers) were commissioned from Fr. Lürssen Werft as general contractor on October 23, 1987. The 745 class is derived from the Schwedeneck-class and was also built as a subcontract at the Kröger shipyards and the Elsflether shipyards.

The hull is made of steel and divided into eight compartments by seven bulkheads. For better maneuvering, cross-thrust steering systems are installed in the fore and aft. The boats are versatile and take the necessary equipment on board in two containers. Fixed equipment includes a ship's crane and accommodation for embarked personnel.

Norton Kiritz. Norton J. Kiritz (1936 - 2006) was an American educator and founder of the Grantsmanship Center.

Early life 
Born in New York City to a shoe salesman, Kiritz spent his early life in the Bronx and was educated at Bronx High School of Science. After enrolling as a scholarship student in the engineering department at Cornell University, Kiritz lost interest in pursuing an engineering degree there and  after relocating to California, he graduated from the University of California, Los Angeles in 1959 with a degree in psychology.

Career 
Kiritz founded the Grantsmanship Center in 1972 as a resource for nonprofit organizations to learn more of the details and best practices in developing their programs and obtaining funding from public and private sources.

In 2000, the California Community Foundation described Kiritz's manual Program Planning and Proposal Writing as ‘’the proposal writer's bible’’. This manual was later updated and expanded in newer editions in order to reflect more-current trends and best practices in the field.

In February 2006, after a long series of struggles with cancer, Kiritz died at age 70. Later that year, Norton Kiritz’s four-decade career in philanthropy education was celebrated in a Los Angeles multimedia life memorial event curated by his widow and successor as the Grantsmanship Center’s chief executive officer, Cathleen Kiritz Elliott. Kiritz Elliott also re-edited and guided the ongoing process of producing updated editions of Kiritz’s magnum opus Program Planning and Proposal Writing in the 2010s and 2020s.

Rhein-class tender. The Type 401 Rhein-class tender was a class of tender ships which was laid down in 1958, christened in 1959 and put into service in 1961 and served as a support unit for the 3rd Schnellboot Squadron until they were decommissioned by 1992. A total of eight ships of this class were built, in addition to the ships Rhine, the Elbe, Main, Neckar, Ruhr, Weser, Werra and Danube.

Development 
Tenders are used as supply and command ships and to supply combat units (FACs, anti-mine ships, submarines) with everything they need at sea. Long endurance at sea are only possible with these mother ships. The tenders take care of the supply of fuel, water and provisions, they also provide workshops, spare parts and tools as well as an infirmary with an operating theater for crews.

After decommissioning, four of the ships were scrapped, three sold to Turkey and one to Greece.

The Type 402 Mosel-class tender consists of three ships (Mosel, Isar, Saar) which are used to supply minesweepers.

The Type 403 Lahn-class tender are used to supply submarines with two ships of this subclass, Lahn and Lech.

Depending on the purpose (FAC or minesweeper tender), different drive concepts were used (diesel-electric drive or diesel engines).

Jetpack man. Jetpack man (also described as guy in a jetpack and Iron Man) is an unknown person or object observed flying what appeared to be an unauthorized jetpack around the Los Angeles area at least five times from 2020 to 2022. Multiple airplane pilots reported seeing the jetpack man at altitudes around .

It is unknown whether each sighting was the same person, or whether it might have been a drone designed to look like a person with a jetpack. Neither jetpacks nor large drones are commonly flown at that altitude or at that distance from land, and there were no sightings of a takeoff or landing. It was theorized by the FBI and the Federal Aviation Administration that the jetpack man was a novelty helium balloon.

Sightings

First sighting
On August 30, 2020, two different airline pilots reported seeing a "guy in a jetpack" hovering near Los Angeles International Airport at ,  from the course of planes on a  final approach.

Second sighting
In November 2020, a Los Angeles Police Department helicopter crew recorded a video of what appeared to be a balloon of the fictional character Jack Skellington from the film The Nightmare Before Christmas. The video was recorded over the Beverly Hills area. A balloon is believed by many to be the explanation for the phenomenon. The behavior of the balloon was similar in the footage to the jetpack man as it was and would later be described.

The LAPD later released the footage in November 2021. The Federal Bureau of Investigation released a statement on the matter, remarking that "the FBI has worked closely with the FAA to investigate reported jet pack sightings in the Los Angeles area, none of which have been verified," and later adding that "One working theory is that pilots might have seen balloons."

Third sighting
On October 14, 2020, China Airlines 006 reported seeing "a flying object like a flight suit jetpack" at .

Fourth sighting
On December 21, 2020, a pilot and flight instructor with Sling Pilot Academy captured the first video of such a flying object, at around  near Palos Verdes and Catalina Island (south of Los Angeles). The academy posted the video to their Instagram account, commenting:The video appears to show a jet pack, but it could also be a drone or some other object. If it is a 'guy in a jet pack' then it remains to be seen whether it is a legal test flight... or related to the jet pack sightings near LAX recently that caused disruptions to air traffic.

Fifth sighting
On July 28, 2021, a pilot reported seeing a flying object that looked like a man in a jetpack, roughly  off the California coast, at . In air traffic control chatter, the flying object was referred to variously as "the UFO" and "Iron Man".

Sixth sighting
A sixth sighting of jetpack man occurred in June 2022 15 miles east of LAX at about .

Euskotren TD2000 series. The Euskotren TD2000 series is an electro-diesel locomotive type operated by Euskotren in the Basque Country, Spain.

History
In 2006, Euskotren awarded Ingeteam the construction of 12 diesel-electric locomotives for 37.5 million euros. The first locomotives were delivered in early 2009, and entered service later that year. The purchase has been criticized due to the low usage of the locomotives, caused by an overestimation of rail freight demand.

Due to lack of use, one of the locomotives was leased to FGC from 2012 to 2017, where it served as the FGC 255 series. In 2015, three of the locomotives were converted to  gauge and sold to FE EP, the national railway of Ecuador.

Naming
Each unit is named after a river of the Basque Country.

Schwedeneck-class multi-purpose ship. The Type 748 Schwedeneck-class multi-purpose ship was a class of multi-purpose ships built for the Wehrtechnische Dienststelle 71 (WTD 71) of the German Navy in Eckernförde and the Marinearsenal Wilhelmshaven. Two units are still in use for the WTD 71.

Development 
As a replacement for the test boats Adolf Bestelmeyer, Friedrich Voge, Rudolf Diesel and Hans Christian Oersted built in the 1940s, three medium test boats, (ship type according to the ship number list) were commissioned from Fr. Lürssen Werft as general contractor. Subcontractors were the Kröger shipyard, the Elsflether shipyard and Nobiskrug. A fourth ship of this class was no longer needed.

The hull is made of steel and divided into nine compartments by eight bulkheads. For better maneuvering, transverse thruster systems with 150 kW each are installed in the fore and aft. The ships are used in a variety of ways and take the required equipment on board in containers. The fixed equipment includes a ship's crane, a swiveling A-frame at the stern, a pinasse and accommodation for embarked test personnel.

The state of Mecklenburg-Western Pomerania bought the Schwedeneck in 2010 and had it converted into a research ship at the Peene shipyard in Wolgast.

Euskotren 950 series. The Euskotren 950 series is an electric multiple unit (EMU) train type operated by Euskotren in the Basque Country, Spain.

History
In June 2014, Euskotren awarded CAF the construction of 28 3-car EMUs for 150 million euros. They are similar to the earlier 900 series, but feature improved accessibility.

The first trainset was delivered in November 2015. The series entered service on the Txorierri line on July 2, 2016. The series gradually replaced the older 200 and 300 series trains, with the last unit being delivered in 2018. Now, they also run local services between Eibar and Ermua, on the Urdaibai line, and on Bilbao metro line 3.

Interior
Each train has 94 seats, with additional space for 202 standing passengers. Internally, the three cars are connected with open gangways. Wheelchair space is provided at one end of the intermediate car, the doors near it are equipped with ramps. All trains have dedicated spaces for passengers carrying bicycles.

Naming
Each unit is named after a mountain of the Basque Country. The first 17 EMUs have the same names as the electric locomotives operated by Ferrocarriles Vascongados (a historical company that preceded Euskotren).

Humboldtine. Humboldtine is a rarely occurring mineral from the mineral class of "organic compounds" with the chemical composition FeC2O4•2H2O and is therefore a water-containing iron(II) oxalate or the iron salt of oxalic acid.

Humboldtine crystallizes in the monoclinic crystal system, but only rarely develops well-formed, tabular to prismatic crystals with a resin-like sheen on the surfaces. It is mostly found in the form of botryoidal or fibrous to earthy aggregates and crusty coatings from dull yellow to brownish yellow or amber yellow in color. It can be transparent to opaque. It can form from hematite in oxalic acid.

With a Mohs hardness of 1.5 to 2, humboldtine is one of the softest minerals and can be scratched with a fingernail.

Etymology and history
Humboldtine was first discovered by August Breithaupt in a weathered brown coal deposit near the municipality of Korozluky in Okres Most in the Czech Republic and described in 1821 by Mariano Eduardo de Rivero y Ustariz (1798-1857), who named the mineral after the German naturalist Alexander von Humboldt.

The mineral was already known and characterized when the IMA was founded (1959). Accordingly, humboldtine is listed as an officially recognized mineral.

Occurrence 
The mineral is known to be found in 30 localities, including Germany, Brazil, the U.K. and Canada.

In 2023, during the digitization of the archive of the , a 75 year old letter from a coal mine owner written in 1949 was found. It mentioned that mineral was found in coal mine near the town of Schwandorf. Analysis of the mineral was done which confirmed the discovery. The discovery doubled the amount of Humboldtine known so far.

Crystal structure
Humboldtine crystallizes monoclinically in the space group C2/c (space group no. 15) with the lattice parameters a = 12.011 Å; b = 5.557 Å; c = 9.920 Å and β = 128.53°, with four formula units per unit cell.

Uses 
It is an important synthetic intermediate and also a key building block for the preparation of various advanced materials.

Hiev-class crane ship. The Type 711 Hiev-class crane ship was a class of floating cranes built for the Marinearsenal of the German Navy in Kiel and Wilhelmshaven

Development 
Both cranes were built from 24 November 1960 for DM 4.3 million each under construction numbers 983 (Hiev) and 984 (Griep) at the Rheinwerft in Duisburg-Walsum and, after completion, relocated to their home ports via the inland waterways. The ship names are related to the task of the floating cranes and come from Low German: Hiev stands for “to lift” and Griep for “to grab”.

Design 
The self-propelled floating cranes have a triple diesel-electric drive, each consisting of a MWM four-stroke 16-cylinder diesel engine with 442 kW, a three-phase generator with 700 kVA, a direct current drive motor with 350 kW and a Voith-Schneider propeller. One of the propellers is in the bow area, the other two in the stern area.

The double-link luffing jib crane is a MAN product. The lifting capacities are 100 t with a radius of 16.2 m and 50 t with a radius of 28.5 m and a maximum hook height of 35 m above the waterline.

A galley, living quarters for twelve people and workshops allow a sea mission of up to ten days.
