Not even NASA with its trillions of dollars gets it spot on and on time on the first attempt. Jack did what he said he would do. I won't bust his balls because of delays because it's not like he did it meaningly. He gets a A for effort, a B for being behind and a A for a great machine. And another A for the worlds only current BNIB wide body. I always believe u have to walk in a mans shoes before you condemn him. I focus on what he has done, not what he hasn't. Everyone knows it was a start up and there are always delays. Shit happens. Jack has achieved. That's what matters. Even a basic lightbulb took many many years and many many thousands of attempts before we got light.
Jack and gang should be proud. Achievement and ahead of time rarely go hand in hand. Let's see the next JJP model. And the next n so on. Then the bigger picture can be judged so to speak. Enjoy WOZ in the meantime. Cheers.
