This article proposes a theoretical biological structure — the Casimir Flight Organ — capable of generating directional, propellantless thrust through the manipulation of quantum vacuum fluctuations at the nanoscale. The mechanism draws on two experimentally verified phenomena: the static Casimir effect and the dynamic Casimir effect, combining them with metamaterial plate geometry, biological piezoelectricity, and principles of neural coordination to describe an organ that could, under sufficiently advanced evolutionary or engineered biology, produce sustained directional flight in both atmosphere and vacuum.The proposal identifies four structural components: nanoscale plate arrays, piezoelectric actuator rings, a quantum coordination core, and a directional tilt control system. Atmospheric compatibility, energy scaling, and biological precedent are each addressed. Several critical physics gaps are acknowledged, most notably the transition from nanoscale Casimir force to macroscale spacetime curvature. This work is intended as a theoretical framework for researchers working at the intersection of quantum vacuum physics, metamaterial engineering, and theoretical biology.
