Just thinking......
What was the route frm JB to Atlanta? Both are north of the equator - JB not much, Atlanta quite a lot - and the last time I was at ASI (25 years ago admittedly) it was south of the equator, not a lot but a bit.
Now, unless things have changed in the world of navigation, a great circle route - allowing for routing restrictions - would take you well north of the equator all the way...
Oh, I should add that I am aware of ETOPS requirements but I still have trouble seeing how ASI was in contention as an ETOPS en route alternate for this sector.
It obviously happened but I'm interested if anyone with more inside info can fill in the gaps.
Cheers
