People often ask the what it's questions when I'm dead heading to & from work. One of the most popular questions
I get is what if both engines quit. Well first of all I want to emphasize how rare of a possibility that is. In the last 30 years the aircraft manufactures have made great progress in making very strong & reliable jet engines. They are tested for hundreds of hours under tough conditions. In one example they spray a fire hose into the engine to see how much water pressure would cause it to lose power. That test far exceeds any major rain you will get in a hurricane. They also test it for severe icing conditions in flight. Its important to know that all aircraft have anti icing systems that uses heat from the engine exhaust to melt any engine ice. If one engine quits, you still have enough power from the other engine for ant-ice protection. Then they simulate a bird strike by throwing a large bird like a turkey into an engine intake while in the wind tunnel. This should be no problem for today's engines. They are design to still work even if it was hit by one,or two birds.
Now, lets say in the rare event that both engines quit? Well then in this case the airplane becomes a glider just like the space shuttle. When the shuttle comes back from orbit , it glides all the way back to Cape Carnaval Space center. Well a jet aircraft can glide to about 100 miles at a typical altitude of most jets such as 35,000 ft. You will pass dozens of airports within a hundred miles easily.
