The specially modified short takeoff/landing (STOL) aircraft that were a hit at EAA AirVenture Oshkosh 2014 will return to Wittman Regional Airport for the 63rd annual convention and fly-in. These aircraft compete at the annual Valdez, Alaska, fly-in and air show each May, and more than a dozen of them will demonstrate their unique capabilities at Oshkosh this year.
