Others said there were FAA regulations that restrict how far the planes can be over water with 2 engines
It’s a safety issue, not plane issue.
Nonsense. The B-757 can be ETOPS, but regardless, non-ETOPS aircraft cross the Atlantic EVERY DAY. Trump’s B-757 could make the trip tomorrow. No special clearances, no special certifications.
Arm-chair pilots? How many Atlantic crossings have they made? Me? Many, many, in two engine airliners.
