The story
The P-3 Orion is a four-engine maritime patrol aircraft that has hunted submarines and watched the seas for over 60 years. Its long endurance lets it loiter for hours far out over open water.
It carries a long 'stinger' tail boom housing a magnetic anomaly detector, which picks up the disturbance a submarine's steel hull makes in Earth's magnetic field.
