So I was thinking, Indianapolis (which is my second home) is home to the Hoosier Dome (later named the RCA Dome), which also just happens to have an inflatable roof. So I did some research and found that the Hoosier Dome hosted the closing ceremonies of the 1987 PanAm Games, which think also has a cauldron. So for the closing ceremonies to be traditional and all, they should have a cauldron inside the stadium, so they could extinguish it to end the games. Now that requires a big flame to be under an inflatable roof, and now I’m rambling on, point is a huge open flame was under an inflatable roof, and the Hoosier Dome did not blow up, I know because I saw it when they deflated it in 2008. So wouldn’t that work the same with BC Place in Vancouver?
