A recent court decision supported a pilots decision to continue to his destination with a four engine aircraft after an engine failure at midrange on a two hour flight rather than landing at the midway point. The argument was that an aircraft will fly on two engines and that the probability of two additional failures was quite small. If the one hour reliability of a single engine is 0.9999 do you agree with the pilots decision? If the aircraft was a three engine jet that will fly on one engine would you agree? Comment on the comparative reliability of the three and four engine Jets in this situation
