First milestone is living to age 85 and maintaining brain integrity. Second related milestone is having physical and mental abilities to build planes from both metals and composites. Maybe the third is still being able to safely fly from 7000′ mountain airport and enjoying the process. Have a couple of more planes to complete in my hangar before I get old.
