Is it possible to fly the distance of 1 ½ times around the world in a prop engine plane without landing? Actually, yes. On June 11, 1930, four Hunter brothers set off to set the record for flight endurance. For the next 553 hours, 41 minutes and 30 seconds they flew around and around and around Illinois. Their plane, “City of Chicago,” was refueled in the air and when repairs had to be made, it was done while the plane was aloft. The landed their plane to a cheering crowd of 75,000 on July 4, 1930 at the Sky Harbor Airport in Chicago.
