Hope that the final report details, what the real cause of this poor decision making was. The PIC failed airmanship. In my opinion it is not much about the rules. If physical there is not enough runway ahead of you, you don't try. And there was plenty of doubt. ATC asked, two crew in row 0. The runway out of their window must have looked short. If you do thousands of take offs, I think they should have an idea how it should look like. And if the numbers don't add up too, why did they try. What was the real pressure behind this decision. And why failed the CRM process.
