Airbubba - "I'd almost bet the 75 minute benign area of ops is still buried somewhere in your OPSPEC's, it seems to be common among U.S. carriers for Caribbean operations. Most folks have never heard of it though. It is a legacy deviation from FAR 121.161 first issued in 1977 and is sometimes called 75 minute ETOPS."
You could be correct. I'm not an OpsSec expert. If I was aware of '75 minute ETOPS benign area of ops' in the past I've used fermented yeast as a catalyst to kill those brain cells.
