I was really getting keyed up watching the count and then at T-13 hearing "Hold Hold Hold" was jarring. But that's life in the rocket business. I was impressed with the pre-launch presentation and how SpaceX is making an effort to educate and excite people about what it is doing. (I put some serious thought into how to phrase the following comment) In my opinion, the company should use a more diverse group of launch day video presenters so that people who don't look like the presenters (so far all Caucasians except for one African-American we've seen in past launches) can see someone who looks more like them and get inspired and excited about the SpaceX mission. In a perfect world what you look like wouldn't matter, but in the real world unfortunately it does. Surely SpaceX has some employees of East Asian or South Asian descent (for example) they could use as presenters? I am confident that SpaceX is not deliberately choosing young attractive white people to be launch day presenters and excluding people who don't look like that. But I think SpaceX needs to put more thought into this issue.
