McDonnell Douglas High Speed Civil Transport. The McDonnell Douglas High Speed Civil Transport was a proposed supersonic airliner design that was the subject of internal and NASA contract studies in 1996. It was envisioned at a time when the company was struggling to compete in the commercial aviation market and would ultimately never progress beyond a paper design.

Design goals envisioned a 300-passenger capacity with a 5,000 nautical mile range. Projected cruise speed was between Mach 1.6 and Mach 2.4.

Design and development
McDonnell Douglas conducted internal and NASA contract studies to determine the market  requirements for a High Speed Civil Transport (HSCT) and resolve environmental, economic and technical issues. "McDD is participating in an international study group exploring the HSCT concept, with Aerospatiale, Boeing, British Aerospace Daimler-Benz, Japan Aircraft Industries, Alenia and Tupolev."

A first flight was envisioned for 2003, with certification projected in 2005–2006. A market for between 500 and 1,500 was also forecast. In the event, none were built and the aircraft remained a paper project. A conceptual design illustration showed a long narrow fuselage with four podded engines under sharply raked fixed delta wings mounted low at mid-fuselage and a swept cruciform tail, looking not unlike the cancelled Boeing 2707.

Yellow Smoke Park Bridge. Yellow Smoke Park Bridge is located on the eastern edge of Denison, Iowa, United States.  Steel was in short supply during World War II as a part of the war effort. Many bridges built across the state were built in this era with timber, especially small-scale bridges.  Heavy flooding washed out 27 bridges and culverts in Crawford County in May 1945.  The county board of supervisors used emergency funds to build new bridges.  They bought several steel superstructures from the Des Moines Steel Company to replace the washed-out spans.  The bowstring arch-truss structures appear to have been designed by H. Gene McKeown, a civil engineer from Council Bluffs.  This bridge is one several similar structures built in the county, and one of five that still remain.  It was moved to serve a pedestrian path in a county park around 1986.  The bridge was listed on the National Register of Historic Places in 1998.

Ara Institute of Canterbury. Ara Institute of Canterbury, often simply referred to as Ara, is an institute of technology in Canterbury, New Zealand. It was formed in 2016 from the merger of Christchurch Polytechnic Institute of Technology (CPIT) and Aoraki Polytechnic.

Ara specialises in applied tertiary training. Subject choices include business, engineering, architecture, nursing, creative arts, hospitality, computing, science, languages, outdoor education, and broadcasting. Programmes range from Level 1 to Level 9. The institute works closely with industry to ensure students have relevant skills for employment, and have a wide range of work placement opportunities.

Each year around 14,000 students enrol at Ara, including many international students. Ara is internationally recognised and has one of the best English language training centres in New Zealand. Over 50 countries are represented among staff and students at Ara.

On 1 April 2020, Ara became a subsidiary of Te Pūkenga (the New Zealand Institute of Skills and Technology) alongside the 15 other institutes of technology and polytechnics (ITPs) in the country.

Campus
Ara has six campuses in Canterbury and North Otago (three in Christchurch and one each in Ashburton, Timaru and Oamaru), making it the largest tertiary institute in the South Island.

The Meaning of Ara
Previously known as CPIT or Christchurch Polytech, Ara was created in 2016 when CPIT and Aoraki Polytechnic merged. Ara is the Māori word for path or journey representing the learning process, the many pathways to success, as well as the routes and rivers that criss-cross the Canterbury Plains.

Underpinning the Ara logo is the phrase 'Ara rau, taumata rau' which translates to 'many pathways, many opportunities'. This phrase captures the varied aspirations of our learners, and recognises that learning is a lifelong undertaking.

Buildings on the City campus, Madras Street, Christchurch 

 Kahukura – This block built for architecture and engineering studies was completed in June 2017 and is named after the Māori for a chief's cloak.
Te Kei – This two-storey building housing executive and administrative staff was completed in 2018 and is named after the Māori for the bow of the canoe.
 Te Puna Wānaka – This is the centre for Māori, Pacific and indigenous studies which was built in 1996. A year long refurbishment to address damage caused by the 2011 Christchurch earthquake was completed for its reopening on 7 July 2021.

PC 1715. The PC 1715 was an office computer produced by VEB Robotron in East Germany starting in 1985. The system featured an 8-bit microprocessor, the U880, a clone of the Zilog Z80. It was built for office work and education, but was also put to some specialist uses, for example an optional interface was available for controlling a pacemaker. The 1715 had minimal graphics and sound capabilities. The price was 19,000 East German marks.

In contrast to the A5120 predecessor, the PC1715 was not built around the K1520 bus standard. There was no back plane, but the main board had 2 58-pin connectors that were largely K1520 compliant, with some signals omitted and replaced with custom internal signals. The floppy controller of the PC1715 used one of those internal bus extensions and was built with discrete components and logic chips, whereas other robotron computers of the 1980s used a clone of an Intel 8272 Floppy disk controller. The floppy controller board clearly appears to be based on the one used in the A5120.

The graphics subsystem on the other hand was part of the main board circuitry and relied on a Intel 8275 compatible CRT controller with a portion of main memory used as video memory.

A second U880 processor was used in the keyboard, together with a small firmware ROM to decode the keyboard matrix and transmit the keycode via a serial link to the main board. Though it was common practice at the time for processors that failed normal quality tests to be reused with much reduced clock frequencies and this may have been the case here.

In 1987, a new version was produced, the PC 1715W (1715M in the Soviet Union). The system was identical to the PC 1715, except the processor was clocked at 4 MHz and the machine had 256KB DRAM.

In total, about 93,000 PC 1715 and PC 1715W units were manufactured. An estimated 50,000 of those were exported to the Soviet Union.

In March 1987, a stamp was issued by the German Democratic Republic featuring the PC 1715. 8 million copies were printed.

Aviation-capable naval vessel. Many present-day naval vessels, aside from aircraft carriers and full-length deck amphibious assault ships, are capable of carrying aircraft. A majority of United States Navy ships have at least a helipad, capable of landing medium-sized helicopters. Many others have decks and even hangars incorporated into the structure of the ship. It has become a standard part of modern ship design to have a deck that supports multiple, medium or large helicopters, as well as being able to house them in a hangar, for protection and maintenance. Aside from carriers and full-length deck amphibious assault ships, the US Navy has 12 classes of commissioned surface warships, 10 of which are aviation-capable. Two of those classes, patrol ships and mine counter-measure ships, are due to be replaced by the littoral combat ship, at which point the entire US Naval surface war fleet will be aviation-capable.

US Navy ships
As of 2016, the current types and classes of US Navy ships, along with their capabilities are as follows:

Along with these types and classes, many of the US navy's non-commissioned ships, specifically those of the Military Sealift Command, are aviation-capable as well. The United States Coast Guard also has cutters that are aviation-capable. Also, with the growing technology in UAVs and UCAVs, virtually every ship afloat has, or will soon have, some type of aviation capability.

Other vessels
The following are examples of other types aviation-capable vessels from other navies around the world:

Other types
 Battlecarrier
 Merchant aircraft carrier
 Submarine aircraft carrier
 Aircraft cruiser
 CAM ship
 Drone carrier
 Fighter catapult ship
 Interdiction Assault Ship
 Seaplane tender
