Overland Train
In the 1950s, LeTourneau Inc. developed several overland trains, essentially oversized semi-trailer trucks that could travel over almost any terrain. Their intention was to be able to handle logistics needs without being dependent on local road or rail systems, allowing them to operate in back-country areas. The US Army had three experimental units built, the largest reaching almost 600 feet (183 m) long, which holds the record for the longest off-road vehicle. Road trains are in use in certain roles today, but the US Army examples and a few derivatives appear to be the only off-road examples built.

The resulting fire killed all 74 people aboard Royston Grange and eight people aboard Tien Chee. Royston Grange's burnt-out hulk was scrapped in Spain in 1979. Royston or Roystone Grange is an 18th-century farmstead next to the site of a medieval monastic grange at Ballidon in Derbyshire, England. Houlder Line had named ships after several English granges, including Royston, since the 1890s. This ship was the company's fifth and last Royston Grange.

Geo-Design in Planning for Bicycling
Cities have increasingly promoted bicycling as a mode of transport as part of their strategy to develop a more sustainable transportation system. Australia is one of the countries that seeks to promote bicycling in a significant manner. There are two primary barriers faced in this effort. The first is the organizational complexity of planning and of implementing cycling-related projects, which can span across different agencies in government at various levels, from federal to local. Second is the lack of a clear framework for effectively planning a bicycling network using multiple data and tools available to these agencies within a limited budget. The use of a geo-design-based, collaborative, and data-driven framework for planning bicycling networks brings various stakeholders, such as transport planners, urban designers, and academics, into the planning practice, thus overcoming the mentioned barriers. Geo-design is an environmental design framework for complex problems involving the collaboration of different teams and stakeholders, supported by digital computing and communication technologies.

List of Starship Flights
Prototypes of the upper stage of the SpaceX Starship have been flown nine times. Designed and operated by private manufacturer SpaceX, the flown prototypes of Starship have been Starhopper, SN5, SN6, SN8, SN9, SN10, SN11, and SN15. Starship is planned to be a fully reusable super heavy-lift launch vehicle and unusual for previous launch vehicle and spacecraft designs, the upper stage of Starship is intended to function both as a second stage to reach orbital velocity on launches from Earth, and also be used in outer space as an on-orbit long-duration spacecraft.
