Backpacks are often the most convenient way to carry your gear, this one is specifically designed for flying with dedicated radio pocket, headset pocket and space for fuel testers and more. For a limited time it comes with a free water bottle holder. Makes a great gift for the Student Pilot starting out this fall.

The rusting of iron. Rusting is the corrosion of iron and readily occurs in the alloy steel. The formation of a reddish brown flakes which loosely adheres to the iron is called rust. Steel is an alloy made of iron and carbon. The carbon atoms in steel greatly increase the strength of the metal.
