Their adversaries are very dangerous and I wouldn't be surprised if they have to disassemble a huge amount of their production to find the error.
I still remember that Facebook Executive mysteriously jumping planes after the Koreans refused to make a Facebook only phone, and the plane having some weird malfunction and the ensuing racist banter by American media. Even the Japanese turned around their flights to SF to check their planes for sabotage, and found some strange errors in their flight systems. Of course they were american boeing airplanes, and they might do well to begin diversifying their fleet if you ask me.
