Also those beasts will fly on one engine to the sun. Each engine on a 777 has more power than all 8 on a B52. Have you seen a 737? The engine of a 777 has the same diameter - as the whole 737 fuselage.
Yes, we know that it can fly on one cylinder... that's why i'm not putting a link to a crash news... Meanwhile, usually losing an engine midflight force you to land at the nearest airport... mostly because you don't have the luxury of the whole "1 engine is enough" when you already lost half of your options... which can totally ruin your timetabul...
