Can a 747 land without engines?

The higher you get, the less dense air is, which reduces friction and allows reaching higher speed. An engine failure means that the plane is going to have less power and will be forced to fly at a lower altitude. That is enough to warrant an emergency landing. The same can be said about the Boeing 747.

How do jet engines deal with rain?

As the incoming air moves into the rotating fan blades, the spinning motion flings the heavier water outward like a centrifuge. The water is then blown through the bypass air ducts that surround the engine core. In this way, the water is carried through the engine without ever entering the combustion chamber.

How much is a jet engine cost?
