There is a passenger side to any event like this.
The airlines make oceanic flying sound like a "done deal." But, it is not. Stuff like this happens. We have no idea how the crew (cabin and flight deck) interacted with the passengers during this event.
Maybe the airlines should be required to provide every oceanic passenger with a letter that they must read and sign, which explains the issues involved with oceanic flights in general and ETOPS in particular.
Why not? It's their butts that are on the line right along with the crews.
