HARLOW: American Airlines this morning has extended its Boeing 737 Max cancellations for a fourth time. This will result in thousands of additional canceled flights through early November. This is all, Jim, of course, because of the grounding of that 737 Max jet.</s>SCIUTTO: And we're also learning it's becoming more likely Boeing's troubles with the 737 Max will now stretch into 2020. CNN Correspondent Tom Foreman is in Washington, joins us now to explain. So, Tom, have they discovered new problems with the jet or is it the solutions to the problems we already knew about aren't sufficient? What's happening?</s>TOM FOREMAN, CNN CORRESPONDENT: A little bit of both seems to be the answer here. I mean, the real fundamental problem here is that every time they seem to be getting close to a finish line on this, the goalpost moves a little further out. And I think the real key to that has been that, as they have looked at the basic airplane, not just this one problem, they've re-examined all sorts of earlier things that they said were fine or they felt were okay, and have started saying, well, is that really okay? One of the questions, for example, being if you go to these manual controls, are they essentially too stiff for some pilots to maneuver? Are they requiring too much energy? American Airlines has expressed some faith in all of this. They have said that they remain confident that impending software updates to the Boeing 737 Max, along with new training elements and developing a coordination with the union partners, will lead to recertification.
