The Advantages of Jets. Jet engines have far fewer moving parts than piston engines, so they are more reliable, safer, and less costly to operate. They burn kerosene, which is less expensive than gasoline, and produce tremendous thrust for their weight. Therefore jet aircraft can be made larger and can fly faster than piston-engine aircraft. Steam propulsion is inherently dangerous, and the early steam engines could be a problem. To power a steam engine, you must produce heat to boil water and make steam. You must then pressurize the steam. It is the pressure, trapped in boilers, that creates the power to drive a piston and subsequently a wheel.
