Thanks for the correction. My first thought was that the IUS had exploded. Never thought there would be a problem with the launch vehicle. But there’s no such thing as a ‘routine’ rocket launch. Each one is unique. Sad day today. It hurts thinking about it.
I will never forget the image of being in the massive Gift Shop, or whatever they called it then, and seeing all of the TV's running the VCR tape of 20+ minutes of debris falling from the sky following the explosion. That tape was for sale at the time and I did not have the presence of mind to buy it right then and there. I returned a few months later and was told that the tape was no longer for sale.
