Buzz didn’t mention it when I went to see him speak last year. He talked for over an hour.
I heard such an astronaut speak for more than an hour, too.
He was derisive in his talk and in the Q&A session flat lied about such things. I knew he was lying easily. It was straight scripted BS. And he wasn’t all that sincere about it but gave it a good college try at sounding hostile and derisive about the whole idea.
I was disgusted. Here he is the hero to the kids and lying to their faces.
