> TL;DR: If ammonium nitrate's chemical instability was the physical fuse, management's strategic misjudgment and the systemic collapse of corporate culture were the deep-rooted detonator. Takata omitted the desiccant to win cost bids, let a "culture of silence" normalize hazards for years, falsified test data for a decade, and severed the market feedback loop — turning a life-saving supplier into a global disaster. Its bankruptcy was not a chemistry failure but a collapse of values: before safety, any cost calculation is a desecration of life. The Fatal Decision: Cost Supremacy Overrides Engineering Common Sense Takata chose ammonium nitrate as its propellant not because of technical superiority, but out of a relentless desire to squeeze costs. Compared with the industry-standard sodium azide, ammonium nitrate was not only cheaper as a raw material but also produced higher gas yield — which meant smaller, lighter inflators and dramatically lower logistics and assembly costs. Yet the engineering consensus was clear: ammonium nitrate is extremely unstable and absolutely requires a desiccant to isolate moisture. In the fierce bidding war of the supply chain, Takata's management made a fatal decision that defied engineering common sense — they omitted the desiccant from production. This was not merely...
