he hand built the majority of this plane (most of the woodwork and metal frames were his work, engine and gauges were off the shelf stuff):
he truly was a special craftsman, with a vast knowledge in everything mechanics, car, machine related.
i talk with his son on a weekly basis, we built a treehouse for my son, i helped him renovating their house, etc, so i watched the whole story from pretty close. his son and his wife were shocked because they thought that he accepted his condition, except he never did. it looks like he wanted to leave on his own terms.
