(Airshow conversation with retired United Capt. regarding ETOP's)
Rumer has it that a United 777 had to shut one down last summer over the Pacific.
Apparently cruised beyond ETOP forcing FAA to re-address the time and distance on 1. Can't confirm never heard anything to come of it.
On a related subject. A close friends son works for either P&W or GE running around the world repairing fan blades on BIG THRUST ENGINES. I've been told that the failure rate on the blades have been higher than the past due to their enormous size.
I understand the blades are pitting and wearing at abnormal rates.
I would prefer 4 any day, at least over the Pacific, but as we all know, the airlines would rather save a few dollars and spend less on fuel.
