This is a biography about the development of the phantom Ki-94 high-altitude fighter, designed by the late Tatsuo Hasegawa, a designer at Tachikawa Aircraft, as B-29 bombers approached Japan (with B-29 blueprints already obtained by spies). *Attached is a CG color photo of the Ki-94, autographed by the late Mr. Hasegawa. Thank you for viewing.
