For very long flights, I would do everything in my power to get a 4 engined jet, even choosing to change airline or date of travel.
I'm actually surprised more people do not think it is important.
10sec:
You seem to understand what implication a engine failure has on a twin, landing within maximum 180/207 minutes. A 4 engine jet however may continue it's journey after a such, and more managers push pilots to do so than not.
Now if you take your other argument into consideration, namely "if one of them fails the other will as well", and if you extend this argument to all four, which jet would you prefer to sit in: The twin who
WILL go and land within the next three hours, or the 4hauler who will have
CONTINUED over the Pacific, Himalaya or North Pole, far away from any alternate??
Happy flying
