Malaysia Airlines Flight MH370 vanished in 2014 with 239 people aboard, and despite years of searching, wreckage and flight recorders were never fully recovered. The film uses that disappearance to examine how commercial aircraft are tracked and why the system failed here: most planes rely on ADS-B, which broadcasts location, speed, and altitude through an onboard transponder, and investigators believe MH370's transponder was manually switched off, letting the aircraft fly undetected for hours. It lays out two proposed fixes, ADS-C, which uses satellite links to confirm a plane's position independent of the transponder, and a fuller space-based tracking network that would flag any deviation from a filed flight path in real time. Cost and privacy tradeoffs get weighed against the alternative, another aircraft lost with no way to locate it. MH370 remains the case study throughout, treated less as an unsolved mystery to dwell on than as the incident that exposed a gap in how aviation tracks its own planes.
