Model airplanes keep flying veteran Jack Dunn airborne

Retired pilot Jack Dunn logged more than 55,000 flying hours during his career. Now he satisfies his urge to "leave the earth" by building and flying radio-controlled model airplanes. Above, Dunn holds one of the many planes in his workshop.

Jack Dunn feels most at home in the air.

He knew from the time he was a child in Georgia that all he wanted to do was fly planes. He built his first model airplane out of match sticks when he was 6 years old, wound a rubber band around its propeller and let it go in his living room. It flew across the room and around a corner before colliding mid-air with a dangling light bulb. His mother scolded him, but Dunn was hooked.
