Real passenger plane transformed into mecha from a bystander's live stream perspective

9:16 vertical screen mobile phone shooting perspective, real passerby live broadcast recording footage, slight handheld shaking, automatic exposure changes, focus pulling, real environment sound recording, distant city skyline clearly visible. An airport runway near the city center, background is a modern metropolis with towering skyscrapers. A large twin-engine wide-body passenger jet is approaching at low altitude preparing to land, landing gear deployed, engine roar is shocking. Just as it is about to touch the ground, the aircraft fuselage begins to undergo mechanical structural reorganization -- wings folding and disassembling, fuselage panels sliding and expanding, complex metal parts precisely splicing, hydraulic structures extending and rotating, gears and armor pieces reconstructing at high speed. Highly complex industrial-grade mechanical transformation animation, realistic metal materials, full sense of weight, mechanical details extremely precise. The plane completely transforms into a giant metal robot, the moment of landing cracks the runway, gravel splashing, shockwave spreading. The robot then rushes towards the city, running at high speed, footsteps crushing the asphalt road, streetlights collapsing, cars being flipped, building glass shattering, smoke and dust filling the air. Hyper-realistic movie-level visuals, realistic physical destruction system, dynamic lighting, particle effects, shocking explosion effects. Overall style maintains "mobile phone authentic live recording texture" but possesses Hollywood-level visual effects and IMAX-level details.
