Searching for a Heartbeat From the Sky - The Nancy Guthrie Case
Can a “Signal Sniffer” Really Locate Nancy Guthrie?Helicopters overhead. Antennas scanning the ground. Reporters talking about searching for a “heartbeat from the sky.”
It sounds futuristic. A pacemaker acting like a beacon. A signal strong enough to guide rescuers from the air.
But here’s the hard question: are these devices really trackable from hundreds of feet above the ground?
Modern pacemakers transmit tiny bursts of data. They are built for medical monitoring, not long-range tracking. So what exactly is a “signal sniffer,” and how much of this is practical science versus public optics?
In high-profile searches, technology can look more powerful than it actually is.
