A look at how America's air traffic control system nearly buckled under its own blind spots, built around historical mid-air collisions and the pressure-cooker environment inside towers like JFK's. The film traces how radar-based tracking, designed decades ago, struggles to keep pace with modern air traffic volume, and reconstructs the chain of errors and gaps in coverage that have led controllers to lose track of aircraft in the past. Interviews and archival footage lay out how these near-misses and crashes pushed the FAA toward NextGen, a satellite-based system meant to give controllers a more precise, real-time picture of every plane in the sky. The film moves between the human side of the story, exhausted controllers and split-second decisions, and the technical side, explaining GPS-based surveillance versus old ground radar in plain terms. It closes on the stakes of the transition: an aviation system still catching up to the technology that could prevent the next disaster.
