Already on the plane. At an altitude of 11,000 meters (36,000 ft). The metal detector went off, but unfortunately they didn't notice that he was wearing a cage!
They also checked it with the handheld detector, which beeped, but they thought it was just the button on his pants. I'm waiting for ideas on how to make fun on how to prank the boy, so that next time they notice what's on it when checking? :)
