Widean, I haven't watched any of his other videos, but if you just read the comments, you'll see people pointing out his errors, so it's not just us. The comments is where I got the info that I posted.
Rocket launches are a unique activity, so they are handled differently than regular air travel, and the investigations are handled the same way all the time - the rocket builder does the investigation, because the FAA doesn't have the ability to do it because the rocket construction is unique to that design. NASA has had two shuttles have issues and debris fell down and could have caused a risk to air travel or other things, and NASA did the investigations, not the FAA.
So the way he talks about SpaceX here is not bringing up valid complaints, which is why I think he sounds negative.
