Apologies if this question has been asked before.
I am a very frequent non-pilot flyer, and always assumed that safety was in part my responsibility. I listen to briefings, check for exits and scan this forum from time to time for news on flight safety.
I had never felt great about flying the atlantic with twin engine planes, but had taken some comfort from ETOPS certification, understanding that the chance of failure was extremely low given the testing and modelling of systems in ETOPS certified planes.
In the face of the documented problems and NTSB warnings, how is the 777 able to maintain its ETOPS rating?
