SpaceX has developed technologies over the last decade to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle first stage ...
Jet bridges are occasionally used at smaller, single-story airports. This is accomplished by a flight of stairs and, in some instances, a wheelchair lift. In this scenario, a passenger proceeds through the gate and then up a flight of stairs to meet the height of the jet bridge. An example of this can be found at South Bend International ...
