So four engines required, each one of which is capable of sustaining the flight of the aircraft.
Then we need to set up a 24/7 air-air refuelling fleet, cruising and ready to deliver fuel mid-ocean crossing, to the (mid-air refuelling-capable) four-engined aircraft, because it doesn’t matter how many engines you have if you lose all the motion lotion due to a defect or damage. After all, the probabilities of losing all the motion lotion are about the same as losing both of the engines on a modern, transport category aircraft.
Run it past ICAO. (That’d be the same ICAO that hasn’t got GADDS through yet, more than seven years after MH370.)
