Desc: This WACO UPF-7, piloted by Jim Franklin, performed in the daily airshows. The plane has mounted underneath, a CJ-610 jet engine from a biz-jet. The radial on the nose pulls it downhill, then the jet spools up, and woosh, it goes back up -- vertical penetration like no WACO ever saw before. Quite a ride for the wing-walker.
Ref: 257-3
