I don't know the name for when you have to bail out and parachute to your destination while the plane continues onward.
Railways (especially in the UK) used to have something like that under the term of "slip coaches": Rear coach(es) were decoupled on the approach to a station – the front portion of the train continued at speed non-stop, while the uncoupled rear portion was braked to a stand (hopefully not stopping too early, because otherwise a rescue engine would have to be dispatched to draw it forward into the station). The heyday of slip coaches was in the early 20th century, although the practice didn't fully die out until 1960.
