Hugh DeHaven was a smart man who lived a long time ago and liked to study how things work. He was very interested in airplanes and how they could fly in the sky. He thought it was important to keep pilots and passengers safe when flying, so he came up with new ideas to make planes safer.
One of his big ideas was to create a better seat belt for pilots so they wouldn't get hurt if the plane suddenly stopped or crashed. He also invented ways to make the controls in the cockpit easier to use, so pilots wouldn't get confused and make mistakes.
Hugh DeHaven worked with other smart people to create new safety standards for airplanes. This means that all planes have to follow certain rules to make sure they are safe when people fly in them.
Thanks to Hugh DeHaven's hard work, we can feel much safer when we fly in airplanes today!
