How Twin-Engine Jets Cross Oceans (ETOPS Explained)

Ever wondered how twin-engine aircraft safely fly over the middle of the Pacific Ocean?

In the past, strict aviation rules forced planes to stay close to land—meaning only four-engine giants could fly long ocean routes.

Everything changed with ETOPS (Extended Twin-Engine Operations), proving that modern aircraft can safely fly for hours on just one engine.

Today, jets like the Boeing 777 can operate over oceans with extreme reliability and efficiency.

Modern aviation proved one thing:

Two highly reliable engines are better than four.
