The existence of this roller coaster was listed in the 1991 ACE Guide To Ride as the former location of the Gillian's Wonderland Pier City Jet. However according to Gillian's Wonderland Pier their City Jet came from Steel Pier where it operated for about 5 years.
If this is the same City Jet, it probably went to Gillian's Wonderland Pier by way of Steel Pier.
Another possibility is this City Jet was relocated to Fun Pier (which later became part of the Moery's Piers complex). Little is known about this City Jet's origins or what became of it. About all this is known is it was damaged in 1984 when a fire destroyed Frankenstein's Castle.
