Take this Douglass DC-3, for example. These planes were early airline transport and used widely in WWII. They are renowned for durability and dependability, with most flying thousands and thousands of hours. AND, they are still used today.
Duggie is in use in a number of ways. At the air show he took jumpers up to altitude so they could jump from a perfectly good aircraft to be part of the air show demonstrations. Duggie is also an educational tool, showing school children about air planes, and encouraging their interest in aviation. Check out the web site on the first photo. If you have children, share the site with them, as well. There is a lot of information as well as activities.
As you can see, Roamin' sure enjoyed his time on the aircraft. In this photo he is checking out the cockpit of the plane. Unfortunately he didn't get to handle the controls.
Basler, a company in Oshkosh, coverts the DC-3 from radial piston engines to turbine engines, bringing these fabulous historic airliners into the 21st Century. This conversion makes them more efficient, fives them a somewhat faster cruise speed, and lengthens the life of the aircraft.
Can you figure out which part of the aircraft Roamin' is standing in? He's outside the craft...that's your only hint.
