I was at the game and it was not the disco ball. It was a large round of glass that covers those high power lights in the ceiling. That could have been seriously dangerous if it hit and broke on a player, fan or anyone else. Those shards in the video are huge. It fell from about 100 feet up and I'll estimate that the round was 12" in diameter. Maybe only part of it fell off or only part landed on the court since it didn't seem like that much glass, but I could clearly see it missing from one of the lights above that area of the court (no reflections like the others). What is this the Kingdome?
