I don't know anything about the actual presentation you saw, but the B-52 mishap you are talking about is probably the 1994 crash of Czar 52. I first learned of it at an aviation safety course where it was used as a case study in command climate. A google search will show you plenty of material and images, but the summary I think the Aviation Safety School used is

I recycled this into a student-led command climate discussion for officers of all services and MOSs at Command and Staff, and I think it worked well.
