Re: Boeing 737MAX Grounded Worldwide Q3 2019

And I find your theories to be pretty wild. The BOD will not allow this to drag until the middle of 2020. How much say BOD has, from your perspective? It is about certification agencies, and there is no guarantee they buy whatever modification Boeing does next as a solution. So assuming it is 2020,...
