Dear Sirs: This letter concerns the skyjacking of Flight 305 on Thanksgiving Eve, 1971, by so-called D.B. Cooper. I would seriously like to offer a theory and some basic facts as to who this individual is.

Of course, I fully realize that the checking of any story requires time and resources, and that I could be completely wrong in my assumption. Nevertheless, should you decide to use my idea, and should it prove worthwhile, is there a reward still in force in this case? Thank you for your time. I await your reply.

Sincerely yours, [REDACTED — b6/b7C]
