[u][b]Travel, vehicles, and Space Technology[/b][/u] The ways in which people travel have not drastically changed. No new forms of transportation have been invented, and the commonly known and understood modes and methods of travel over distance through the use of vehicles have not greatly changed. But the types of those vehicles and how they are powered, propelled and other such aspects have changed to some degree, as the Heavenfall gave room for the development and implementation of new vehicles and the networks that support them. Wheeled and ground transport have not really changed a great deal. As mentioned above, electric and hybrid vehicles have become much more common and the ways in which such vehicles are powered has changed. Hydrogen fuel cells are used in many commercial, private, military and industrial vehicles, and biofuels in others. Rail transportation for heavy loads over large distances is also used regularly, and has in fact seen something of a renaissance in some countries for mass public transportation, with light rail (such as trams, subways and monorails) and metro-style systems becoming remarkably commonplace in many cities, and utilising the new freedom to build and develop as an motivating factor for new development. Passenger rail systems started to come back across the USA as well, and long abandoned or neglected railway lines were given a new lease of life as new services were implemented. Worldwide, electrification of railways increased, along with the use of hydrogen fuel cells, as with other types of transportation. Water transport remains much the same; as with other methods, the fuel used has changed, but the actual transport itself remains the same, only in some cases with more implementation of more advanced and varied types. Hovercraft have been utilised more heavily over short ranges as ferries and for purposes of search-and-rescue or patrol. Hydrofoils have become more common in the shallow waters they are most at home in. In the air, aeroplanes and helicopters still persist and have diversified into thousands of types, marks and models, civilian and military alike and for all manner of purposes. Tilt-rotor aircraft have become popular as short-range feeder airliners from city centers or for regional purposes. Civilian helicopter transport and transport heliports have become more common as well. Supersonic airliners have seen a resurgence, as has a move away from the 'traditional' shape of airliner as a slow uptake, with aircraft like the [url=https://en.wikipedia.org/wiki/Boeing_Sonic_Cruiser]Sonic Cruiser[/url] seeing some uptake for point-to-point flights. Space travel and transportation have slowly increased following the Heavenfall. As the destruction affected many of the launch sites, platforms and locations used, it has taken time to build them back up. In doing so, a number of projects have been revisited and put into practice. Rockets are still used for some payloads and purposes, but increasingly the use of Spaceplanes and other Single-Stage To Orbit - SSTO - platforms has been adopted. In the most ambitious show of adopting space travel and technology, the NCAA has begun construction of a space elevator on the equator, but progress is slow and extremely resource intensive, even for a nation the size of the NCAA, though the world is watching with eager eyes.
