Can there be a steel plane?


Airplanes do use steel, but they are not completely made out of steel. Steel is sturdy and strong, but also very heavy. The amount of lift needed to get a steel airplane off the ground makes it a bad choice for the main material of an airplane. However, steel is often used in very particular areas of an airplane, like the landing gear! Nowadays, most commercial airplanes use a high amount of aluminum and other materials.
