From 2019 (YouTube Version): Aero-News Talks With The Airplane's Builder
One of the many unique airplanes at AirVenture 2018 was a 1/3-scale B-17 bomber built by Jack Bally, who talked about the 17-year project with Aero-News at the show last summer. Bally said that the idea was born over "too much beer one night with a bunch of buddies" as they talked about what kind of airplane they could build that would be the only one of its kind. They settled on the B-17, because as far as they knew, there were no flying 4-engine scale models WWII
