Looks like an N1 blade failure in the parked aircraft picture. There were two engines offered by Boeing for the 777. This one which has a bit more power than the Rolls Royce Trent 892, rated at 90,000 pounds of thrust on each side. The Rolls is more reliable. Still think about 90,000 pounds of thrust, more thrust than the original Redstone Missile that put John Glen into obit, and the B777 has two of them.
In any case the 777 has been a very successful aircraft, reliable and does the job. The engines are not Boeings problems other than hanging them on the aircraft, they are the manufacturers problems.
