The stakes are high for Boeing; they are higher for the government of Ethiopia.
I really doubt that, it is just more spin from Boeing's creative marketing division. Unlike Boeing, this incident does not have the possibility (however remote) of forcing Ethiopia into bankruptcy. The issues facing the government of Ethiopia are far more significant than who gets the blame for a jet crash, and if it were in fact the fault of a pilot panicking and doing the wrong thing than that would actually be a fairly simple thing for the government to shrug off, especially in a country were so many have already died in war. Mechanical failure could be either the fault of Boeing or the airline; it would be much harder for them if for example the tail had fallen off and there was a report that the plane had been involved in a ramp incident.Nobody in the United States is worried about losing an election because of the Atlas Air crash.
