The Red Thread №001: D. B. Cooper — Three Theories That Won't Die

The Black Letter established what the record can prove.

Now we follow what happens when that record runs out.

More than fifty years after D. B. Cooper disappeared from Northwest Orient Flight 305, the unanswered questions have produced theories ranging from plausible to extraordinary.

In the first episode of The Red Thread, we pull on three of the most persistent.

Could microscopic particles discovered on Cooper’s tie connect him to America’s aerospace or specialty-metals industries?

Was convicted skyjacker Richard Floyd McCoy Jr. actually D. B. Cooper—and did investigators dismiss the connection too quickly?

And what if the most fundamental assumption in the case is wrong? What if Cooper didn’t jump where investigators believed he did—or never made the jump at all?

The evidence gets us only so far.

After that, the threads begin.

The history is real.

The connections are yours to make.

Keep pulling the thread.

The Red Thread is a companion series from the Black Chamber Society exploring the theories, disputed connections, conspiracies, and unanswered questions that begin where the documented record ends.
