These videos are more than one narrow, they give demonstrations, examples, visit restricted areas and get to touch reallly cool machinery. This isnt a 3 minute speedrun world record stretched to a 45 minute video.

Even those 3 minute speed runs can be 45 minutes long because they're explaining all the glitches and tricks they're using in the run and showing all the nuance you wouldn't get in just the 3 minute run.
