Create an ultra-realistic cinematic video of an airplane flying steadily through the sky that transforms mid-flight into a modern rocket and rapidly ascends toward the upper atmosphere. The sequence should begin with the airplane in stable forward motion under natural lighting, maintaining realistic scale, perspective, and aerodynamics. During the transformation, the airplane must reconfigure through visible mechanical movement: wings retract and fold inward, engines compress and merge into a central propulsion system, and the fuselage reshapes into a sleek cylindrical rocket body. Panels should slide, rotate, and lock into place with clear mechanical articulation, including subtle sparks, heat glow, and internal structural detail. Avoid smooth morphing — the transformation must feel engineered and physically plausible. Once the rocket form is complete, the engine ignites with an intense, bright exhaust plume featuring a white-hot core and glowing edges. Add strong heat distortion and air turbulence behind the thrust. The rocket then sharply pitches upward and accelerates rapidly toward the upper atmosphere, leaving a long, powerful exhaust trail. Motion should follow realistic physics with increasing speed, visible acceleration, and dynamic motion blur. The sky should subtly transition from lower atmosphere tones to deeper blue as altitude increases. Maintain a single continuous shot with consistent perspective, cinematic lighting, high contrast, and realistic textures. Avoid visual artifacts, distortion, or abrupt cuts. The overall feel should be high-energy, cinematic, and physically grounded.
