KEILAR: Just weeks after a Lion Air Boeing 737 Max 8 crashed in the sea off Indonesia and months before a 737 Max operated by Ethiopian Air crashed in Ethiopia, pilots complained to a Boeing officials about the anti-stall system on the planes. An audio of that exchange has emerged, first airing on CBS News.</s>PILOT: We flat out deserve to know what is on our airplanes.</s>BOEING: I don't disagree.</s>PILOT: These guys didn't even know the damn system was on the airplane, nor did anybody else.</s>BOEING: I don't know that understanding this system would've changed the outcome on this.</s>KEILAR: Well, during a hearing, members of the House Transportation Subcommittee grilled officials from the FAA and the NTSB on that very topic. We have CNN's Tom Foreman here on this story. What did we learn from this hearing?</s>TOM FOREMAN, CNN CORRESPONDENT: What we learned is that there is still very distinct camps in this. Remember, what we're talking about here is, when Boeing put in this update on this plane, this thing called the MCAS system, on their newest type of plane, a new feature, it was intended to stabilize the plane in flight. But in both of these crashes, people believe that it nosed the plane down in a way that pilots could not recover from. Boeing's position, and some of the people in this hearing today in Congress, their position was more or less to say, look, we think that the pilots should have been able to handle this. They should have been able to figure it out, follow procedures, everything's fine. And then there are others, including pilots like this who are saying, if you don't even know that the system is there and you have very little time to recover, how can you push it off on the pilots right now. This was a design flaw and Boeing has to be held responsible for it. Those camps were very clear.
