Stagger, I think you
are actually arguing what I said above.
The 747 will have started the sector on 4-engines (as around 99.99% of 747s do!).
So, if you are suggesting that, having already had
one engine failure (i.e. flying on 3 engines) it is then
still more likely to have a second failure than a twin on 2 engines (i.e. no failures - yet), then my suggestion above is indeed correct.
