The planned climax to the ceremony was delayed by a technical glitch of a malfunctioned limit switch, which also severed the communications cable to override the program. This meant that the Olympic flame was suspended in mid-air for about four minutes, rather than immediately rising up the waterfall to the top of the stadium. In interviews after the ceremony, the organizers stated that when the cause of the problem was discovered, engineers overrode the program and the cauldron continued its course, and the ceremony concluded with a fireworks display. 20-years later, some engineers stated it was fixed through a backup radio signal to the cauldron. Moreover, the gas bottles for the cauldron were close to empty before it was attached to a main gas line, and the backup flames were missing.
