You dont need both engines to fly

The idea of an engine giving out mid-flight sounds frightening, but every commercial airplane can safely fly with just one engine. Operating with half the engine power can make a plane less fuel-efficient and may reduce its range, but planes are designed and tested for such situations, as Popular Mechanics reported. Any plane scheduled on a long-distance route, especially those that fly over oceans or through uninhabited areas like the Arctic, must be certified by the Federal Aviation Administration (FAA) forExtended-range Twin Operations(ETOPS), which is basically how long it can fly with one engine. The Boeing Dreamliner iscertified for ETOPS-330, which means it can fly for 330 minutes (thats five and a half hours) with just one engine.

In fact, most airplanes can fly for a surprisingly long distance with no engine at all, thanks to something called glide ratio. Due to careful aeronautical engineering, a Boeing 747 can glide for two miles for every 1,000 feet they are above the ground, which is usually more than enough time to get everyone safely to the ground.
