Your Plane Flew 3 Hours From Land — On Purpose | How ETOPS Works

On February 1st, 1985, a twin-engine jet took off from Boston for Paris with eleven FAA inspectors on board — because if that flight failed, twins might never cross an ocean. It didn't fail. It changed aviation forever. This is the story of ETOPS: the number that decides how far your plane is allowed to fly from the nearest airport, why the 60-minute rule locked twins out of the oceans for thirty years, how ETOPS-120, 180, 240, 330 and 370 opened the planet to two-engine jets, and the exact diversion math your crew checks before every ocean crossing. Stay to the end for the one number that decides whether your flight can cross the ocean — and where to find it.
