Yeah given the delayed and soon upcoming actual human scheduled flight, this would have been maybe nicer to put off a couple days... just optics but still...
"It's actually good optics that it exploded, because it shows they aren't changing their schedules for the sake of optics. Political pressure to make the schedule fit the public's feelings was a major contributor to the Challenger disaster. So, having a tank blow up the day before a manned launch shows that SpaceX has overcome the challenges of the past."
(See? That spin makes the turbopump look like a stator. If I have a point it's that talking about optics is pointless, because you can make the optics anything you want by casting the right light.)
