ENAER Ñamcú. The ENAER ECH-02 Ñamcú was a single-engine, two-seat, light aircraft, designed and built by the Chilean manufacturer ENAER. A first prototype flew in 1989, and while the joint venture company Euro-ENAER was set up to build the aircraft in the Netherlands as the Euro-Enaer Eaglet, these plans failed when Euro-ENAER went bankrupt in 2002.

Design and development
The Chilean Air Force established an aircraft manufacturing arm, IndAer, in 1980, which began by assembling Piper PA-28 Dakotas and building the ENAER T-35 Pillán  military light trainer, which was developed by Piper for manufacture in Chile. IndAer became ENAER (Empresa Nacional de Aeronáutica de Chile), a separate state-owned company, in 1984.  

In 1986, ENAER began work on its first entirely indigenous aircraft, a two-seat, single-engined light aircraft suitable for use by flying clubs as a training aircraft. As such, the project (at first known as the Avion Livano (light aircraft)), was to be inexpensive, with a price of US$70,000 claimed in 1991.

The Ñamcú was a low-wing tractor monoplane with a fixed nosewheel undercarriage. It was of all-composite construction, with most of the structure made of glassfibre and polyurethane sandwich material, while the wing spars were made of a mixture of glassfibre and carbon fibre. The crew of two sat side by side in a fully enclosed cockpit, with gull-wing doors. A  Textron Lycoming O-235-N2C flat-four piston engine drove a two-bladed fixed-pitch propeller.

The first prototype made its maiden flight in April 1989, with three more prototypes following, one of which crashed on 11 February 1992 following a bird strike, killing the pilot.

After attempts to interest the Chilean Air Force in the Ñamcú failed, ENAER set up Euro-ENAER, a joint venture with the Delft University of Technology and Dutch investors, to certify the aircraft as airworthy in the Netherlands under European regulations, with ENAER hoping to sell 50 aircraft per year, at a price which had now increased to US$100,000 an aircraft. By 1998, it was planned to assemble a modified version of the aircraft, powered by a  Textron Lycoming O-320-D2A engine, in a new factory in the Netherlands. Certification of the Eaglet was expected by late that year, with the aircraft having a price of $120,000. In early 1999, Euro-ENAER was blaming poor weather and difficulties with the Joint Aviation Authorities for delays in certification for the Eaglet, whose unit price had now reached US$160,000, although the company was now forecasting annual sales of 50 per year in Europe and 200 a year in America. Euro-ENAER finally managed to certify the Eaglet in 2001, but the company announced it needed additional funding to start production. These efforts failed, however, and Euro-ENAER was declared bankrupt later that year.

Multi-Payload Processing Facility. The Multi-Payload Processing Facility (MPPF) is a facility at Kennedy Space Center constructed by NASA in either 1994 or 1995 and used for spacecraft and payload processing. Prior to being assigned the role of processing the Orion spacecraft, the MPPF was used to process solely non-hazardous payloads.

Layout 

The interior of the primary MPPF building is divided into a low bay, high bay, and equipment airlock. 

The high bay is certified for the processing of hazardous materials such as high-pressure gasses, hypergolic propellant, ammonia, oxygen, and fluorocarbons. It has a usable floor space of  with a ceiling height of . It is equipped with an  bridge crane with a hook height of  and a  vertical door. The low bay has a usable floor space of  with a ceiling height of . Both the high bay and low bay are class 100,000 cleanrooms. 

The airlock has a usable floor space of  with a ceiling height of  and is a class 300,000 cleanroom. It is equipped with a  door.

Usage 
After its construction, the MPPF was used for the processing of both Space Shuttle and Launch Services Program payloads. Following the end of the Shuttle program in 2011, it is slated to process the Orion spacecraft, and is also available to process hazardous or non-hazardous Space Launch System (SLS) payloads if necessary.

Design work on upgrading the MPPF for Orion processing began in 2007 during the Constellation program, but actual installation and modification work began in 2013.

Orion spacecraft processing will be performed by the Spacecraft and Offline Operations team while the SLS is being stacked on the Mobile Launcher in the Vehicle Assembly Building. During this time flight commodities will be loaded into the spacecraft. These flight commodities include monomethyl hydrazine fuel and nitrogen tetroxide oxidizer used in Orion's propulsion systems, ammonia coolant for thermal control, and Freon for the service module's radiator system. The MPPF will also be used to de-service Orion capsules that have returned from space and remove any residual flight commodities.

Due to the hazardous materials involved, loading and unloading of flight commodities will be remotely monitored and controlled from one of the firing rooms inside the Launch Control Center and performed by technicians wearing Self Contained Atmospheric Protective Ensemble (SCAPE) hazmat suits.

On January 16 2021, The Artemis 1 Orion spacecraft began fueling and pre-launch servicing in the MPPF following a handover to exploration ground systems.

Novaer T-Xc. The Novaer T-Xc is a prototype two-seat training aircraft designed and built by in Brazil by Novaer.

Design and development
The T-Xc is a low-wing, cantilever monoplane with retractable tricycle landing gear. It has an enclosed cockpit with two side-by-side configuration seats. It has a single Lycoming IO-540 piston engine in tractor configuration. 

The T-Xc was developed to replace the Neiva Universal in Brazilian Air Force service. It was designed by Joseph Kovacs based on his K-51 aerobatic aircraft project. The prototype first flew from São José dos Campos Airport on 22 August 2014. A proposed development is a four-seat utility aircraft variant.

Rollfix-Eilwagen. The Rollfix-Eilwagen GmbH (Rollfix Express Car Ltd.) was a German manufacturer of motor vehicles in Wandsbek quarter of Hamburg, Germany, located at Stubbenhuk 10, today the location of the Henry-Nannen Journalist School.

The company was founded in 1923 or earlier. Another source indicates 1926 as founding year. 1923 began the production and marketing of three wheeler of the brand Rollfix. The company was specialized on commercial vehicles. In addition, some were created Passenger cars.

1933 it came to a comparison procedure. Successor company became the 1934 Rollfix-Werke Frederic Schröder KG with the brand name Motrix.

The first vehicles had the single wheel behind. Between the two front wheels was an open platform for cargo. Alternatively, a box was available. A tubular frame formed the base. A two-stroke engine was placeded in front of the chaindriven rear wheel. First 127 cc engines were supplied by DKW and had optional 297 cc. The driver sat on a saddle over the rear wheel. An advertisement shows a two seats in row version. It was steered with a handlebar. The original price was 1000 Reichsmark.

In 1927 a steering wheel superseded the handlebar. The engines supplier changed to the ILO-Motorenwerke, Pinneberg. Prices rose from 1260 to 1600 Reichsmark.

In 1932 or 1933, a redesign was marketed. The single wheel was now in front. The model Hamburg was a flatbed truck with closed cab. It was designed for 500 kg payload. The ILO engine was 200 cc. On the same frame a rig for 1.5 tons payload was designed. The new price was 2580 Reichsmark was described as too high for successful marketing.

Also two passenger car variants  were offered in 1933, although unclear if ever produced. One is called tail-heavy sedan with four seats and the other as Station wagon "Kombinationskraftwagen" with folding top.

In the same year the Rollfix record appeared on the market. It was a two-seater with a single rear wheel. The roof was open, but not the back wall or rear window. The engine was mounted in the rear. He drove over a three-speed gearbox with reverse gear and a chain on the rear wheel. A 200 cc single-cylinder engine with 5.5 HP and another 300 cc single-cylinder engine with 7.5 HP as well as a 400 cc two-cylinder engine with 11 HP were offered. The 323 cm long vehicle had a 234 cm wheelbase and a 136 cm gauge. One sample still exists.
