Rocket Engine

A rocket engine is a device that uses stored fuel to achieve high-speed propulsion.

History
They are used for space ships, like the ones NASA uses.

An experimental rocket engine was kept in an abandoned rocket assembly plant near New York City. Doctor Octopus used the plant as a hideout when he kidnapped Felicia Hardy and J. Jonah Jameson. Spider-Man used a dynamo to trap the villain which activated the rocket. Spider-Man saved Jameson and Hardy before the rocket test could begin.
