Interestingly, those "horribly, hilariously bad PowerPoint" presentations tend to have better content-to-noise ratio than the pretty ones.

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.
On the other hand this presentation is not that bad, at least it does not have bullet lists nested five levels deep where text size does not match the nesting levels and such things.
