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.

Rust is another name for iron oxide, which occurs when iron or an alloy that contains iron, like steel, is exposed to oxygen and moisture for a long period of time. Over time, the oxygen combines with the metal at an atomic level, forming a new compound called an oxide and weakening the bonds of the metal itself.lthough some people refer to rust generally as oxidation, that term is much more general; although rust forms when iron undergoes oxidation, not all oxidation forms rust. Only iron or alloys that contain iron can rust, but other metals can corrode in similar ways. The main catalyst for the rusting process is water.
