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.

Rusting is the general term used to describe the corrosion of iron and its alloys, such as steel. The process of rust involves the way various materials react with oxygen, which results in the chemical compound of rust. When iron combines with oxygen, iron oxide forms.usting is the general term used to describe the corrosion of iron and its alloys, such as steel.
