They used to make a plane called the duraplane, that was almost indestructable that you could probably still find at a swap meet. It's a beatuful thing to have a plane that can take big time abuse. I had a Ace All-star that could be cartwheeled down the runway or flown into a pole (with witnesses), and with straightening of the rubberband mounted wings or the tweeking of the wire landing gear back, you could be back  flying.
