The attraction is designed to allow smaller children a chance to ride a coaster; 35" is the minimum height requirement. Opened in 1996, the attraction utilized some components from existing Mickey's Birthdayland / Mickey's Starland including the barn which is said to the the petting zoo from the previous incarnations of Toontown Fair, specifically Grandma Duck's Petting Farm. (Hmm, we wonder if the teenagers liked that attraction.)
The ride takes visitors on a ride under the pretense of Goofy as a flight instructor, takes some traditional twists and turns after the initial climb, and features a 'crash landing' of sorts as riders wind through the barn itself towards then end.
All in all, the Barnstormer is a quick ride and clocks in at under 1 minute which keeps the lines moving and in line with expectations for smaller children looking to take their first roller coaster ride in the Parks.
