I just hope Blue hasn't gone from extremely methodological and conservative to push as hard as possible and fly as quickly as possible. I mean it seems like doing a few maybe 3 or 4, full wet dress rehearsals. where they fully fuel the NG and take the count down all the way to 0 but don't launch would have made a lot of sense before actually trying to launch. It is very reasonable to expect to find issues with each actual real world, wet dress rehearsal and then to give themselves the proper time to address each issue fully. Simulated computer count downs are NOT the same a real world tests.
Also a few more hot test fires of the 1st stage would of made sense. Better to find issues on the ground rather than 50 seconds into the 1st flight. Just doing these rather simple tests should give them a huge increase in confidence to launch, and to set expectations for the public and media.
It seems like some strange artificial goals like, launching before 2025 and launching on Bezos' birthday are actually driving Blue's launch goals rather than sound engineering choices. After 25 years Blue's team isn't going to flip and switch their culture quickly.
They also set expectations rather high and I have read plenty of articles about this flight is just a formality and NG is going to be flying about 3-4 flights this year with full payloads. Wow, considering Blue has never made it to orbit and this is their 1st 2 stage rocket, that is rather bold and opens the door to plenty of criticism if there is a failure.
Pushing too hard, also mean short cuts can be taken that compromise sound engineering. "Not knowing what you don't know" is always the hardest problem with brand new systems.
