The A-10. A beautiful cannon with a jet built around it. It is an awesome tool for the job needed. it would be a crying shame to retire this aircraft.
Getting rid of the A-10 is like getting rid of a wrench because the design is outdated.
The cockpit is a titanium bathtub with an airplane built around it. The devastating, rapid fire gatling gun on the nose that can drill through tank armour was added to make the Wart Hog sexy. Heard that one from an A-10 pilot.
