> but if all of the planes can be reviewed to confirm basic airworthiness, at some point you have to let them fly again.

Doesn’t this review and confirmation take place before they even go into service? So if they missed these bolts on the last review, what’s to say they won’t miss them or something equally as important on the next review?

“Oh think of the economy” is the worst excuse I can imagine to let these back into service.
