Download "Cap" Cornish, Indiana Pilot: Navigating the Century of by Ruth Ann Ingraham PDF

By Ruth Ann Ingraham

Clarence "Cap" Cornish was once an Indiana pilot whose existence spanned all yet 5 years of the Century of Flight. Born in Canada in 1898, Cornish grew up in citadel Wayne, Indiana. He started flying on the age of 19, piloting a "Jenny" airplane in the course of global warfare I, and persevered to fly for the subsequent seventy-eight years. In 1995, on the age of ninety-seven, he was once famous through Guinness international documents because the world’s oldest actively flying pilot.

The mid-1920s to the mid-1950s have been Cornish’s so much lively years in aviation. in the course of that interval, sod runways gave method to asphalt and urban; navigation developed from the iron rail compass to radar; runways that after have been defined at evening with cans of oil crowned off with flaming gas now shimmered with multicolored electrical lighting; rather than being filled subsequent to mailbags in open-air cockpits, passengers sat very easily in streamlined, pressurized cabins. within the early part of that period, Cornish played aerobatics and gained air races. He went directly to run a full-service flying enterprise, served as leader pilot for the citadel Wayne News-Sentinel, controlled the city’s municipal airport, helped display screen and keep secure skies above the continental usa in the course of international warfare II, and directed Indiana’s first Aeronautics Commission.

Dedicating his lifestyles to flight and its many ramifications, Cornish helped consultant the practical improvement of aviation because it grew from infancy to adulthood. via his many own reviews, the tale of flight nationally is performed out.
