ceiling dropping as the spikes begin to descend slowly toward them. In the next area, large stone blocks released from the ceiling (triggered by the diamond-shaped stones below) are barely kept in place by wooden wedges and supports. Further on, in the Rotunda Calendar, pulling on a rope triggers responses from Dr. Dunfor Pullit, an out-of-sight archeologist supported by the rope beneath the sarcophagus stone. Various crates throughout the queue contain some significant features; one marked with the number "990 6753" refers to the number on the crate holding the Ark of the Covenant in Raiders of the Lost Ark. Another crate is marked "Deliver to Club Obi Wan", referring to a fictional club at the beginning of Indiana Jones and the Temple of Doom, itself a reference to the character Obi Wan Kenobi from Star Wars. Eventually, guests encounter a projection of a newsreel of the discovery, followed by safety instructions delivered by Sallah. Mickey Mouse and Minnie Mouse appear on the cover of a copy of Life Magazine in Professor Jones' office. Ride experience At the loading area, guests board the troop transport. Through the radio, Sallah (voiced by Bob Joles) reminds the tourists to fasten their seat belts and points out a problem with the brakes (in earlier versions of the ride, there would alternatively be problems with the gas pedal or the steering wheel). The transport takes off, past a cluster of mirrors concealing the maintenance dock entrance, and turns a corner into the Chamber of Destiny, where guests are presented with three doors. One of the three doors begins to glow more brightly than the other two, and Mara (Voiced by James Earl Jones) announces which gift the passengers have chosen to receive. The doors open, and the passengers enter the Hall of Promise, where the idol of Mara resides at the end of the hall. As originally built, the Chamber of Destiny only had one actual operating door and corridor. Since the ride's opening, the room's walls and ceiling were designed to rotate across the working doorway and a set of four façades (two on each side of the real doorway) so that three "doors" are always visible at any given time. Each of the doors are lit differently based on which particular chamber has been randomly chosen, and decoy tracks leading to the other doors have been used to enhance the effect. In
