Maglev Train on Failing Suspension Bridge

the prompt

Hyper-realistic cinematic action sequence, 15 seconds, 16:9.  A colossal suspension bridge spans a canyon nearly twenty kilometers wide. An experimental maglev train races across it at extreme speed as the bridge begins catastrophically failing from one end. Towers twist, cables snap under immense tension, entire roadway sections collapse into the abyss, yet the train never slows. The camera alternates between low tracking beside the rails, helicopter flybys, bridge-mounted shots, cockpit POV, and sweeping IMAX aerials that reveal the enormous scale of the collapsing structure. Final shot: the train clears the final gap milliseconds before the remaining bridge disappears into the canyon.  Style: IMAX realism, believable structural physics, massive engineering scale, crystal-clear action, cinematic lighting.
