Rather than a simple gravity - powered drop, however, the elevator is pulled downwards, causing most riders to rise off their seats, held down by a seat belt . At least once during the drop sequence, wide elevator doors in front of the riders open to reveal a view of the park from a height of 157 ft (48 m), however the drop is only 130 ft (40 m), the height of a 13 - story building . The elevator drops at a top speed of 39 miles per hour (63 km / h). In the Hollywood Studios version, the back of the "Hollywood Tower Hotel" sign partially obstructs the view (the on - ride camera is located here, recording the ride for video or a photograph to be purchased later). </P> <P> Randomized patterns of drops and lifts have been added, where the ride vehicle will drop or rise various distances at different intervals . Other added effects include projected images of the breaking window, wind effects, lightning flashes, and ominous blue - lit figures of the five ghostly original riders . These changes were made so that each trip on The Twilight Zone Tower of Terror is a slightly different experience . The ride system was reprogrammed, in its fourth conversion, so that the ride allows for any number Template: Exaggeration of randomized drops and lifts . When guests enter the drop shaft, a computer randomly chooses one of four drop profiles, one of which is a modified version of the ride's third incarnation . Regardless of the number of randomized drops and lifts, each drop sequence always features one "faux drop" meant to startle the riders, and one complete drop through the entire tower at the top speed of 39 miles per hour (63 km / h). </P>
