Sky9, I agree with you, always have. The 2 engine ETOPS has to do with economy. It has proven to be safe so the 4 engine planes are going away because of competition. When they built the B52 they needed 8 engines to make it fly, now they only need 2. I think the FAA should look at their own regulations and realize that BA didn't violate them by continuing because they had more than two engines.
