Does anyone remember this, because I have brought it up with friends around my age and nobody does, but I don't think I hallucinated it. Right after a Steelers-Colts game in Baltimore (Bert Jones era), a plane crashed into the upper deck at Memorial Stadium. I don't think anyone was killed or seriously hurt, but I still remember the newspaper picture of showing the plane crashed into the stands through the goal posts with a headline like "3 points" or something like that.
Steelers destroyed the Colts so a lot of people had left before the game was over.
