I have a problem with saying its the bean counters who dictate the lengthy ETOPS as in several cases it has taken one high fatality crash to take down an airline (TWA, Pan Am for example). What are the 4 engine options? A380 which has had its very near major fatal crash due to one engine failing and the B748. For my millions of miles of trans-Atlantic and trans-Pacific flights, I never felt less secure when the airlines I flew switched from 4 or 3 engine airlines to twins. But then again I am an engineer with a great deal of statistical experience. Today I would have more concern flying a B707 or DC-8 on any of those routes despite having half the engines. That is thanks to brilliant engineering advances.
