Reading through the older part of this thread it dawned on me just how radical it was when passenger ETOPS came into being and how the 757 was the first 'small' aircraft to do longer over water routes, when before it was 3 or 4-holer or nothing.
Or a 2-holer 767.
TWA started flying them across the pond in 1985, whereas the 757 wasn't ETOPS-certified (120 mins) until the following year.
