Good news, folks. I got a PM at the DZ from a young man named John who says that his history teacher is talking about the DB Cooper skyjacking and has recommended that the students read the DZ and THIS site.
He was mostly asking about eye witnesses and who is still alive, conversant, etc.
As it turns out, the class is in NY, and I have invited myself to talk with the class during my foray Back East to attend my sister's wedding, September 23- October 14.
