pilots weren't that familiar with this automated system we all know at mcas because boeing told regulators during development of the plane pilots wouldn't really encounter it that much so they didn't need to know that much about it. this former pilot's concerns first came to light last week as well, publicly, when we got ahold, cnn got ahold, of these internal messages he was trading with another employee saying he had concerns about how this automated system was working's he, himself, was having trouble controlling the plane in the flight simulator. this is something certainly the department of justice, which is probing the boeing, whether they misled regulators and in probing the certification and design of this plane, this is something they're definitely going to look at as well. >> an important report. thank you. a wildfire in california that just started last night but has grown to more than 10,000
