So every plane, train and automobile that went missing in the past 9 years did so without this system offering help?

[ceejayoz]

When have trains gone missing?

[quietpain]

It sounded nice

Well….

There is a movie called closely watched trains which is humorous but not relevant.

These systems are generally never used to solve low-level crimes. When they are, parallel-construction is used to avoid publicizing their existence. These systems are reserved for direct threats to national interests.

Perhaps they went missing when it was cloudy?

From the article: "trained to locate the sources of electromagnetic emissions with wavelengths ranging from roughly 2 meters down to 2 centimeters"

These types of signals wouldn't be obscured by clouds, presumably.

[ehsankia]

wouldn't some IR go through clouds? I thought that was the point of using IR.

That being said, the more important question is, how's the temporal resolution.

[sneak]

Yes. These systems are for control, not general purpose law enforcement.
