The metal detectors were not installed because of any specific threat, but rather as an added deterrent that would help make families feel safer in crowds, according to a Disney executive, who spoke on the condition of anonymity because the company bans the public discussion of its security practices.

Universal Parks & Resorts added permanent metal detectors at the entrances of their theme parks (and at the "ride entrance" for high-intensity coasters like Incredible Hulk and VelociCoaster) as part of a comprehensive security and safety strategy. The primary reason is to prevent "prohibited items"—such as weapons or large glass containers—from entering the guest areas, ensuring a safe environment for families. However, the metal detectors at specific rides in 2026 serve an additional, crucial safety function: preventing loose items from being brought onto high-speed attractions. Items like phones, coins, or keys can become lethal "projectiles" at 70 mph, posing a severe risk of injury to other riders or guests walking below the tracks. After several incidents in the mid-2010s where guests were injured by flying objects, Universal became the industry leader in "zero-tolerance" loose item policies. These detectors ensure that every guest uses the provided lockers for their personal belongings, maintaining a "sterile" environment for the ride's high-G maneuvers where even a small coin could cause a catastrophic injury if it were to strike someone in the face.
