VALLEJO (CBS13) - A new Superman ride is nearly ready at Six Flags Discovery Kingdom in Vallejo. Crews lifted a giant "S" into place Thursday on the 15-story Superman Ultimate Flight ride.

The colon-free Superman Ultimate Flight ride at Six Flags Discovery Kingdom will replace Pandemonium, a $6.5-million Gerstlauer spinning coaster that debuted in 2008 as Tony Hawk’s Big Spin.
