I had seen the KAMAN name many times in the music industry but never equated it to the KAMAN helicopter name. Interesting.
I know he had a hobby of raising seeing eye dogs for the blind. German Shepherds I think. He tried to select the best ones for the job. They say he measured his success by how many people were guided by his dogs , and how many lives were saved by his helicopters. Those are small markets with big rewards.
