of us ever want to go through. you re shutting certain things down to isolate the problem. malaysian authorities don t know when the plane s acars system, which beams down information about the health of the plane, stopped working. the acars lost acars transmission at 1:07. we don t know when it was switched off after that. in a normal flight acars should have transmitted information about how the plane was flying, engine data, fuel burn and any maintenance discrepancies, pilots say it s abnormal to voluntarily shut acars off. and we also learned today from malaysian authorities, they have not found any evidence from any telephone company that anyone on board was trying to call or text out, but they say they re still checking into those phone records. there are millions of them. a lot of people are looking for those, too.
