Next, derived from this, a question: Is a 747 / 380 on two engines after a random initial failure and no diversion followed by a second random failure just as flyable, stable and 'safe' as a 777 on one engine (assuming for both no more engine failures)
Ref. the above - is it valid to discuss/compare an aircraft which has had TWO separate failures with an aircraft that's just had ONE ? Should we not discuss the 747 / 380 with two engine failures compared to a 777 with two engine failures ..... using your criteria of "random failure" - Apples to apples and all that !
..... I guess we can talk about the probability of a 747 losing two and the probability of a 777 losing two (I'm told it's the same) but moving to the real world .... what is the effect ? Bearing in mind we have been unable to think of an incident/accident where a four engine jet aircraft "continuing" on three after a "random failure" has had a problem - it's been going on since the mid fifties !
