That's some really cool info! Great video!

Nice! Thanks.

David, with the last two (and possibly 3rd) attempts to launch SLS, could you make a video detailing about scrubbings of rocket launches. The reason is the big question that I've been hearing (and admittedly I also ask) how come are these problems like the melfuntion engine sensor, and now a big fuel leak are being discovered just now and not weeks or months before the launch date.
