In 1980, Sea World opened a set of bumper boats located in a small lake in the centre of the Viking's Revenge Flume Ride.

[9][10] Alan Griffith Architect formed a strong working relationship with Warner Bros. International Recreation Enterprises on the ride.

[13] The ride's theming, special effects, props and audio-animatronics were designed, supplied and installed by Alder Constructions, Sanderson Group and Showtronix.

Zeitgeist Design and Production's Ryan Harmon served as the Director of Show Development for Warner Bros. International Recreation Enterprises, where he conceived, wrote, and managed the design team for Warner Bros. Movie World Germany's worth of rides, shows and attractions, including Das Bermuda Dreieck.

The ride's special effects were not sufficiently tested and therefore didn't operate until Parques Reunidos' acquisition of Movie Park Germany on 17 May 2010.

Bermuda Triangle originally featured a revolving load and unload platform which increased the ride's capacity.

[27] For example, some of the NTSC CRT video projection screens in the ride clearly displayed "No Signal" or "Replace Lamp" messages.

"[30] In early December 2010, the maintenance page was changed for a third time to read, "Bermuda Triangle is temporarily closed.

"[31] A few days later, Sea World stated on their Facebook page that the Bermuda Triangle had been permanently closed to make way an exciting new future attraction.

[32] After sitting dormant for close to one and a half years, Sea World applied for a permit to demolish the ride and the interior of the show building.

One of the volcanoes and the bamboo on the queue area were demolished and removed to make room for Star Trek: Operation Enterprise in 2015.

[35] In 2019, Bermuda Triangle - Alien Encounter was renamed Area 51 - Top Secret, and got a complete renovation, though the dark ride scenes inside the show building stayed nearly the same.

The windows on the bride building above the station were replaced by video screens, showing animations of military planes and UFOs.

A staff member in a Coast Guard uniform appeared at the front of the queue and ushered the group of riders up a set of stairs into the pre-show room.

The riders would pass a display of 1940s fighter planes being dismantled by a group of aliens, as well as a set of force fields with abducted civilians from various periods of history trapped inside.

The audio commentary from the boat speakers would reveal that one of the coast guards, Clark, is affiliated with the aliens and subsequently disappears to join them.

Audio from Clark within the volcano warns the riders of the aliens' return while the boat is then turned towards the main conveyor lift hill.
