My personal favorite example of a "NASA-style, bad PowerPoint presentation" is a SCRUM meeting involving a deck of slides with ~20 lines of text per slide. The SCRUM master involved was an employee of Accenture, IIRC. [Edit: And yes, the deck by itself had an impressively high information content.]

NASA and its contractors (which, in my experience, do most of the work attributed to NASA) have a weird, self-reinforcing cycle of decision-making by PowerPoint such that slide decks are important, necessary, and ubiquitous and therefore almost universally bad. Tufte's example of of a presentation burying the lede that the Shuttle will get blowed up is just one consequence.
