Silberpfeil is German for Silverarrow and is the name used in Schwarzkopf catalogues.
The layout has a single vertical loop in its center with a diameter of 40 feet. The track passes through the middle of the loop. The ride also incorporates a helix.
3 trains with 5 cars per train. In each car, riders are arranged 2 across in 2 rows, for a total of 20 riders per train.
The first known installation travelled the German fair circuit. It started operation in 1979 and was owned by showman company Robrahn. It later travelled in Africa with Magic World Amusement Park under the name Looping Star. It now operates during the Rand Show, where it has been stationary since 2011.
The other travelling model is Space Witch, located in Croatia. It has previously operated at four amusement parks in the United Kingdom. Its first known location was Ocean Beach Fun Fair, where it is known to have operated in the mid-1980s. It has since operated at Camelot Theme Park, Dreamland Margate and Loudoun Castle where it sat standing but not operating for five years after the park closed in 2010.
The only stationary installation was Scorpion at Busch Gardens Tampa in the United States. This roller coaster opened on May 16, 1980 and remains operating to this day.
A silver arrow model has operated at OK Corral in France during the 1980s but which of the two travelling models it was is not known.
