Just months before a second deadly crash of a Boeing 737 Max airplane, American Airlines pilots reportedly confronted a Boeing official about a computerized anti-stall system.
The meeting between the pilots and Boeing happened in November -- just weeks after an October crash of a Lion Air 737 Max into the Java Sea, and four months before a 737 Max operated by Ethiopian Air crashed in Ethiopia.
CBS News reports that audio of a Boeing official is heard telling pilots that software changes were coming, perhaps in as little as six weeks, but that the company didn't want to hurry the process.
The pilots indicated they weren't aware of the 737 Max's computerized stability program -- the Maneuvering Characteristics Augmentation System, or MCAS.
Boeing's 737 Max 8 and 9 planes were grounded worldwide after the Ethiopian Air crash in March.
Between the Lion Air and Ethiopian Airlines crashes, 346 people were killed.
