Well I suppose I could have said it better, but I think most airline bean counters will agree. A 4 engine aircraft will never cost you less than the same opertion of a 2 engine aircraft.
Safetywise, I undertand the advantages of 4 vs 2, but realistically out of all the millions of flights how many have had multiple inflight failures? Percentage wise you would be more likely to win the lottery in six different countries on the same day and then repeat it again the next..
