The same millimeter wave-length scanning that sees through your clothes at TSA’s very personal pre-flight inspections in airports could also provide a new type of heads-up display for pilots. With an ability to distinguish power lines and other finely-resolved images in otherwise total visual blackouts, the technology could find a place in navigation, searches, and even private flying. A few drawbacks stand in the way, however. Extremely high frequency MMW devices sense objects at a range just below that of the lowest frequency infrared light. The high frequency allows a high level of discrimination in imaging. Used in automobiles for applications such as radar braking and adaptive cruise control, the potential for adapting such devices to weather flying is promising. Used today in military helicopters, it is highly useful in places like Afghanistan, where blackouts of Biblical proportions darken mountain passes at incredibly high density altitudes. Operation Eagle Claw, the 1979 rescue attempt of 400 American prisoners in Iran was …
