I don't see how - Boeing "hotly denied" there was a technical fault, I didn't. Neither did Airbus or EASA.
Furthermore, Boeing's denials came in the wake of two fatal crashes and a near-miss. So far in this case we have no fatalities and very few details of the incident itself. I have to wonder that if flash2002's information is correct, why has there been very little in the way of media attention? Normally an incident of the severity he's claiming would cause the press to be awash with reports of screaming passengers, deadly plunges and narrow avoidance of schools and orphanages.
