Planes Fly Without Engine

via

Planes have multiple redundant systems in place, and that includes engines. If one of the plane’s engines gives out, there’s a secondary one to take its place. But even if the plane suffers complete engine failure, not all is lost.

Thanks to their aerodynamic design, planes can glide about 1.5 nautical miles for every 1,000 feet of altitude. Considering commercial jets cruise at around 30,000 feet, that gives an engineless jet around 45 nautical miles – that’s around 51 miles or 83 kilometers – to fly before touching the ground, which gives the pilot plenty of time to land safely.
