"Boeing decided late last year that those failures were not a security issue, but the company and the F.A.A. later concluded that they represented a threat after further investigation and analysis." Translation: Boeing tried to ignore it until the F.A.A. told them to cut it out. Obviously this is a bit of a dead horse by now but if anyone still thinks that regulatory capture (I'm deliberatly using an adverserial term like capture despite the fact that this process was a consensual one) that allows Boeing and other manufacturers as much oversight and freedom in their own regulation is a good thing, then they need to wake up.
