The timing on this could not have been worse. Makes the 787 fiasco look minor in comparison. Airplane grounded, and now even if they get it all fixed and approved by all the different regulatory agencies, what airline is going to take delivery of a new plane when they've got plenty in storage and no customers to fill them?
Boeing might as well relax, take time and sort out any little bug that was reported in the aircrafts short operational life span, and hope by the time they have all those bugs worked out flying is beginning to resume and airlines are ready to accept delivery.
Airbus doesn't have the same exact problem, but the problem of taking new planes, even if they are proven to work just fine, is going to be a problem for airlines losing money every single day.
What's the point of an open door policy if inside the open door sits a closed mind?
