The detonated groundbreaking for the Space Science building also included a band of student picketers. There are quite a few photos of them, all carefully “X”ed out on the contact sheet, I suppose so no one would accidentally use them in some public relations material. Here’s an example:
I think the Thresher’s recounting of the incident is pitch perfect, with every participant maintaining character from beginning to end. Farces always work best when one party doesn’t quite appreciate the gag. I laughed hard. I can’t help myself.
I also agree that it would have been a lot cooler if there had been a bigger explosion. Probably too risky, though.
