Interesting quote, supposedly in a letter by the LOT Safety Pilot, according to
AVHerald reporting on the LOT B787 incident
From RR bulletins it is clear that the shut down of one engine dramatically increases the likelihood of the other engine failing.
And another quote from the letter:
As we all know while analyzing our case with the engine shut down on our flight from Cancun to Warsaw we were very close to serious trouble. The "good" engine has experienced 3 seconds of "ENGINE SURGE" which could have led to its shut down.
The acronym ETOPS Engines Turning Or People Swimming, long used tongue in cheek, almost became reality��
