Another day, another fiasco at the biggest US airline carrier, and this time it is oddly reminiscent of the conditions surrounding the melting ice-cube that is Tesla.

Bloomberg News reported on Thursday that Barr has recused himself because his former law firm is representing Boeing. Reuters and other outlets reported in March that federal prosecutors aided by the FBI were scrutinizing the development of the 737 MAX jetliners. Boeing did not immediately commen
