Same here, that's why I posted the link.
Anyway, I think SpaceX's engineers are extremely under pressure right now. These missions are extremely risky, everybody knows how difficult is this field and I personally believe that the amount of pressure the team is facing, it's consistently increasing the potential risk of a failure.
SpaceX is a private company and, like all the other private companies in the earth, it has the goal to make money and make investors happy. Every single failure of the company is a big hit on the brand and a loss of millions and millions of dollars, this put the team under an excessive amount of pressure.
