I have nothing to gain by SpaceX failing. I wish them all the best. I'm just stating what I think is pretty obvious - that this was a massive PR exercise, apart from anything else. My BS detector goes into overdrive at times like that.
When you mount cameras on a landing barge, you would expect there to be a high likelihood of them being damaged or affected in some way when your rocket lands. So you do the obvious thing, and setup a redundant camera feed somewhere at a distance. Previous test landings at sea had a chase plane. Where was that this time?
