Could a reasonably loaded but lightly fueled CO 767 manage to get out of BHD-SNN, be precleared and land back in from a direct crossing? (per BA's LCY-SNN-JFK-LCY plan)
This could then assume the role of the current SNN-EWR 757 also although it would suck for Shannonites to have a stop added eastbound similar to the summer Air Transat service.
