Yet another entry from the Six Flags chain (this one in Arlington, Texas), when Titan was built in 2001, it was the longest roller coaster at a Six Flags park, coming in at 5,280 ft. (1,609 m) and lasting a full 3½ minutes. The highlight is surely the camelback and double-helix turn that results in a G-force of up to 4.5, lasting 6 sickening seconds. One other noteworthy element is that the Titan has a drop greater than its climb. After ascending 245 ft. (75 m) into the air, you suddenly plummet 255 ft. (78 m) into a tunnel.
